Part 2: Sorting Imprints

Point A: Appropriation of techniques that were historically used to append imprints able to grant marks of quality and acknowledgement are now readjusted.

Argument 1 : Watermarking as an aesthetic enhancement, a mark of quality to a user imprint.

Watermarks in libraries and archives

Watermarks in the publishing business

Argument 2 : Library stamps providing a body of evidence for determining both the circumstance and date of acquisition, questioning on ownership and acquisition.

Research focus

Examine the repercussion of publishing businesses creating body of evidence against downloaders and how it is opposed to the idea of libraries as a place to access knowledge and to create a community.

Summary

In this chapter, I will start by addressing how language and techniques from libraries and archives were appropriated by commercial distribution channels as a way to create accountability for users who illegally download, distribute and make available copyrighted material. This is done by leaving imprints like the user geolocation, IP addresses, mac addresses, email addresses, etc. Sharing copyrighted material is easy and one can even do it without knowing it. Publishers started to set strategies to limit access to illegal copies. Focused on watermarking in the realm of publishing I will explore what services create and append them. What traces can be left? What kind of information can we spot? Is there any impact on platform users that are constantly reminded that a book has DRM?

SORTING IMPRINTS

Background on Watermarking

The internet as a carrier of digital media changed how we share music, books, video and other media. The integration of digital watermarks is becoming more and more popular to fight the fast-paced spaces opened to share pirated material. The research on watermarks is currently being shaped to strengthen watermarks, embedding robustness with respect to compression, image-processing operations, and cryptographic attacks (Shih, 2017). We now understand watermarks as being both digital and physical, but they are not new phenomena, and it is relevant to know where they come from.

The art of papermaking has its roots in China in the 1st Century. The process was first documented in China in 105 A.D. and ascribed to Cai Lun (Basbanes, 2014). Watermarks only appeared later in 1282. Watermarking happens during the process of making a sheet of paper whilst the paper is still wet. Watermarks are a result of changing the thickness of a specific part of the paper, creating a highlighted area and as a result, its shadow. We track the beginning of watermarks in the town of Fabriano (Hunter, 1987). It is essential to acknowledge the historical importance of the Italian city of Fabriano. From the name "Fabriano", in Latin "Faber > Făbrĭcĭus", meaning "craftsman, artificer, maker" (Latin Dictionary and Grammar Resources - Latdict, n.d.). The practical skills in forging metal and shaping wire were crucial for building the frames used to remove excess water, gather the pulp and to start forming the first sheets of paper.

Watermarks analogue Intention

The history of watermarks is still relatively obscure. It is not possible to fully trace back their ancient significance. A few different theories have been discussed on what was the actual purpose and use of these venerable watermarks. One that I came across with was to help with the production of the sheets of paper. Using them to identifying the size of the frames and the sheets of paper produced by these. (Hunter, 1987) Another hypothesis is that the craftsmen that were working in the production of paper were illiterate. Watermarks were then a strategy of appealing with pictures or symbols. This way of communicating a specification would lead to a smaller chance of creating misunderstandings. The first applications of watermarks compel these possibilities, but it is also possible that in parallel these may be an artistic production of the papermakers. These can also be no more than a fashionable imprint left by the artists making the frames, as a way to identify themselves, creating then an aesthetic enhancement or a signature of quality. (Watkins, 1990)

Watermarks are now valuable to establish provenance to manufacturers of papers, paper mills and manuscripts. These also provide evidence about the movement of paper across Europe, Africa and the Middle East. The use of watermarks was then a critical factor in recognition of paper quality contributing to the increasing desire of specific papers. It is wrong to immediately establish the provenance of a book to one particular place solely based on the watermarks due to the commercial trades of paper. While an Italian watermark may be found in a specific sheet of paper, this would only set provenance to where the paper was manufactured and not its afterlife. Watermarks would comprise graphics such as animals, plants and sacramental imagery but also were representations of geographical territories and in general depictions of Western culture. In Umbria, Italy, for example, the Benedictine monasteries endorsed the 3-hilled mount topped with a cross as their symbol. Developed by the French and Venetians, we identify watermarks imagery of the tre lune/three crescent moons. These strategies were adopted because of Muslims in the Ottoman market. They were expected to choose in favour of papers with these kinds of imagery rather than a Christian cross or other similar motifs. (makingmanuscriptsblog, 2017)

Connecting watermarks and library stamps

There is an active link between watermarks and the introduction of library stamps — both creating a body of evidence when trying to establish connections in a collection. Library stamps are also perceived as an imprint left visible and sometimes glued. Able to question ownership and acquisition. In libraries, books were stamped to record property of books. The relation was created between the physical medium and the library adding traces of provenance to the collection. Library stamps would not be related to the readers of a book, nor they were intended to do so. These connections would happen connecting circumstance and date of acquisition and creating relations in the library itself.

Though library stamps are helpful when determining the time frame and history of an item in a collection, the process of adding the stamps is not necessarily performed when a book enters a collection. The method of adding this imprint could happen later on. Unlike watermarks where it is unlikely that the act of tempering the paper fibres doesn't occur in simultaneous to when a paper sheet is made, stamps were commonly applied later from the date of item acquisition. This lead to mistakes that are now widely recognized. Along with stamps, to build a body of evidence for determining both the circumstance and date of acquisition clues may be found on bindings, bookplates or inscriptions. (Duffy, 2013)

A shift into Watermarks Digital Intention

Watermarks got more significant with the introduction of paper currency. One of the notable shifts I identify is when they are first applied to a banknote paper in England, by a papermaker named Rice Watkins in 1697 (Mockford, 2014). Watermarks were added as a way to deter counterfeits and making the act of forging more difficult, enabling easier targeting to the ones who were doing it. In England, 1773, the death penalty was extended to those who would create watermarks with the name of the Bank of England.

Just as in paper money, watermarks are now used to establish authenticity and their digital implementation, started to get more popular. Emil Hembrooke patented the first digital watermark, "Identification of sound and like signals", US Patent 3,004,104 Filed 1954, Issued 1961. In the US patent, we can read: "The present invention makes possible the identification of the origin of a musical presentation and thereby constitutes an effective means of preventing such piracy" (J. Cox and L. Miller, 2002).

In the 1990's the interest in watermarks increased drastically. Currently one can find them in various forms of copyrighted watermarked material. Nowadays, as most information and data are stored in digital formats and not in physical ones, being able to provide legitimacy and to prove authenticity is progressively representing a more urgent task. (Shih, 2017) Digital watermarks are mostly known as being visual. The normalization of their use in photographs, on video stored on DVDs is a reality by now. In trial software, these also appear often. Instead of restricting the use of a programme, while exporting the final version of the work watermarks are appended. I read this action almost as an arrogant way of advertisement and capitalizing on the users. We are held responsible for using software and at the same time, we are targeted as a commodity. It might be read as a message where we are made aware that money will be made from their users in any way possible.

Appropriation in Publishing

Another significant shift on the use of watermarks happens with their appropriation in the publishing business. Watermarks are now used to create a body of evidence on users, adding traces that relate to the subject more precisely with geolocation, IP addresses, mac addresses, email addresses, etc. An excellent example of this is phenomena is Verso Books publisher. They sell their books in an online ebook store. In this store, Verso books appends a new page in the begging of each book with the downloaders name and his' or her's email address. It also watermarks the IP address of the downloader in the footer of the first page of every chapter.

During my research, I stumbled across an article about different forms of DRM. In this article, the writer starts by giving a disclaimer where he begins by portraiting himself as "a supporter of milder types of DRM like digital watermarks". What caught my attention was how the mode of address changed when he started to identify all the unnecessary strategies implemented by Verso Books in their ebooks. More important we can understand that their watermarks didn't pass unnoticed to the store users. A source interviewed states: "Personally, I felt like I was constantly being sent a stalker's note saying, 'I know where you live.' It put me off reading the books entirely." (Hoffelder, 2014) The increase of imprints that identify us as downloaders and as printers is alarming. Verso Books are calling out their users as pirates and companies, such as BooXtream are making this possible, using us as an asset to capitalize on.

I was then able to identify the company that develops the watermarks to Verso Books. It is a Dutch DRM company called "BooXtream®". It is worrying how they portray themselves; the first quality that they promote on their DRM methods is traceability. We can read in a bold font: "A publication that has been BooXtreamed can be traced back to the shop and even to the individual customer." (BooXtream, n.d.) Watermarks are now perceived as something to fear, used to make us feel uncomfortable. Surveillance might be quickly spotted as it commonly happens with CCTV because we can establish a physical connection with it, we can see it, we can choose a different path to walk from it or even try to disguise ourselves. We were able to accept that digital surveillance is a reality, but we didn't feel a close connection to it yet. I consider that digital watermarks are a vehicle establishing this direct connection. It is still tricky, though, to predict what will be the impact of these techniques if users are afraid to share an ebook that they bought and paid for.

Surveillance in publishing not only manifests itself in obvious ways. Another article that I came across was from the Electronic Frontier Foundation, raising awareness of the Machine Identification Code. First published by the PC World as "Government Uses Color Laser Printer Technology to Track Documents" in 2004, this code is formed by a pattern of dots that are appended to every printed page. The printer software adds it in the process of printing. These are almost imperceptible yellow dots carrying information as the date of print, time and the serial number of the machine. Similar technology is used when you try to scan a banknote. A sequence of yellow dots in the printed in the paper triggers the printer to add a striped pattern on the top of the copy, preventing you from copying it.

I delved into trying to understand if this code was still in use, and I had to be able to prove its existence for myself. I started by using methods to identify these invisible dots, such as UV lights, different printers, from HP to Canon and from Inkjet to Lasers printers. Almost when I was giving up, disappointed with all the time invested in this, I started to reverse engineer this machine identification code and implementing my own. While creating messages printed in minimal font size and scanning these printed pages, I began to understand better how to turn them visible. With a new scanner with a resolution of 1200 dpi and after inverting the colours, they suddenly appear. Just as by magic, a mesh of my messages and the tracking dots started to emerge. Ultimately, I was able to identify them in all the printers provided by the school in the Blaak building. It is worrying that this hidden code is infiltrated in documents and can be seen by anyone. They are not only used in case you are a suspect of a crime, but they are also available for anyone at all times. Coming across with them made me rethink what did it mean to publish in print, how safe is it, and how it might affect the ones who depend on printed forms of publishing.

During this second chapter, I explored the progression of watermarks. From their background, until their appropriation, as an asset to incite fear, self-awareness, and to remotely control and constrain user actions. It was essential for the development of my project to emphasize the value of ancient watermarks at this moment. During the next chapter, I will expand my research from the point of view, where I consider the early framework of watermarks crucial to prevail. I desire to demonstrate that what lies at the heart of their use is their ability to portrait crucial interrupted actions and moments in history, granting insights into hidden processes of fabrication documented in the sheets of paper. While at the same time carrying clues to comprehend their artisans, the historical timeframes and different imagery. I will then extrapolate on how the use of digital watermarks can still be prominent apart from what I recognize as their misappropriation, exploring that the current attitude towards digital watermarking is not the only valid. I focused than my research on how the discourse around these reinforcements of copyright can be flipped around. I will delve into how tactics that seem mainly negative can be re-appropriated.
