Add a QR code on photos. One of the new types of watermarks introduced in uMark 4 is QR code watermark. What is a QR code? A QR code is a code like a Barcode which contains encoded information and can be scanned to read that information. You might have seen the square black pattern of QR code somewhere, in a magazine or newspaper, on a billboard or a flyer. Download uMark For Windows and Mac.

QR codes are a great way to pass information along to people on their mobile devices. A very common use of QR codes is to put links in the form of a QR code so people looking at the code can just scan the code and browse to your link instead having to manually type it in their browser.

You can do the same thing by adding your link as a QR code on your photos as a watermark. When you do that a QR Code Settings window will open up where you can write the text you want to be converted to QR code. You can write your name or just put a link to your website, blog, Facebook profile or portfolio in there. As you are typing the text you can see a QR code being generated on the photo.

You can set the size of the QR code. The size can either be in proportion to the photo being watermarked or it can be a fixed pixel size. You can also select whether the background of the QR code should be white or transparent. QR code with white background is easier to scan. Finally you can set the position for the QR code. Like all other watermarks in uMark, you can either select one of the 9 predefined positions or place the QR code at a specific postilion. You can even drag the QR code around to place it at a specific postilion.

After you are done setting the various options for the QR code, click on the OK button. If you wish you can add more watermarks or you can save the watermarked images by clicking on the Save Images button. When you share these photos with QR code on top of them around people may scan the code out of curiosity and can browse to your site effortlessly. Scan the QR code on following photo and see where it takes you.Shopping now. There is no reason not to with free shipping deals and deep discounts at Watermark Software.

Luckily there are things you can do to put an end to code smuggling and with luck sometimes you can track where your stolen code is being used. Here is what to do:. You can tag your source code with certain keywords i. The true reality however is that it is hard to prevent code smuggling without having data leakage prevention controls on each workstation and server. I would recommend reading this chapter excerpt SearchSoftwareQuality promoted, How to make your software tamperproof.

Inside you will learn about watermarking and tamperproofing, which is basically checking to make sure all of your coding is in solid, good-working order and then adding characters to personalize it. This makes it very recognizable to the original coder and would confuse others trying to use it of what the function of each line of code is.

Software theft, also known as software piracy, is the act of copying a legitimate application and illegally distributing that software, either free or for profit. Legal methods to protect software producers such as copyright laws, patents and license agreements 1 do not always dissuade people from stealing software, especially in emerging markets where the price of software is high and incomes are low. Ethical arguments, such as fair compensation for producers, by software manufacturers, law enforcement agencies and industry lobbyists also do little to counter software piracy.

It can then be extracted by an extractor or verified by a recogniser to prove ownership of software. The former extracts the original watermark, while the latter merely confirms the presence of a watermark 4. It is also possible to embed a unique customer identifier in each copy of the software distributed which allows the software company to identify the individual that pirated the software. It is necessary that the watermark is hidden so that it cannot be detected and removed. However, in some cases it is desirable that a watermark is fragile in the sense that if semantics preserving transformations are performed on the software the watermark becomes invalid.

This is useful in the context of software licensing where any changes to a program could disable it.

watermarking code

Watermarking techniques are used extensively in the entertainment industry to identify multimedia files such as audio and video files, and the concept has extended into the software industry. Watermarking does not aim to make a program hard to steal or indecipherable like obfuscation but it discourages theft as thieves know that they could be identified. A manual watermark is inserted by the programmer of the application, rather than a using a third-party automatic tool. Some semi-automatic watermarking systems also exist e.

The Collberg-Thomborson algorithm implemented in Sandmark 7 - where a programmer inserts markers into a program during development and the finished software is then augmented by a software watermarking tool.

Watermarks can be classified as either visible, where the recongiser is public knowledge or invisible where the recongniser, or some component such as an encryption keyis not public knowledge. Visible watermarks can act as a deterrent but also show an adversary the location of a watermark making the task of removing the watermark easier.

Software watermarks present several implementation problems and many of the current watermarking algorithms are vulnerable to attack. Watermarked software must meet the following conditions:. Perhaps the most difficult problem to solve is keeping the watermark hidden from attackers while, at the same time, allowing the software owner to efficiently extract the watermark when needed.

If the watermark is too easy to extract then an attacker would be able to extract the watermark too. If a watermark is too well hidden then the software owner may not be able to find the watermark, in order to extract it. Some watermark tools such as Sandmark 7 use markers to designate the position of the stored watermark - this is problematic as it poses a risk of exposing the watermark to an adversary.

Watermarks should be resilient to semantics preserving transformations and ideally it should be possible to recognise a watermark from a partial program. Semantics preserving transformations, by definition, result in programs which are syntactically different from the original, but whose behaviour is the same. The attacker can attempt, by performing such transformations, to produce a semantically equivalent program with the watermark removed.

Redundancy and recognition with a probability threshold may help with these problems 8. The watermark code must be locally indistinguishable from the rest of the program so that it is hidden from adversaries 9. For example, imagine a watermark which consists of a dummy method with variables - this kind of method will probably stand out in a simple analysis of the software such as using software metrics techniques 10 It could be difficult to programatically generate code which is indecipherable from the human-generated program code but statisical analysis of the original program could help in generating suitable watermarks 8.

Ideally, software watermarks should be resilient to decompilation-recompilation attacks, as decompilation of Java is possible though not perfect The cost of embedding a software watermark can be divided into two areas: developer time and embedding cost. The former simply quantifies the time that a developer spends embedding a watermark, while the latter quantifies the execution time of a software watermarking tool.

Embedding costs are not a significant problem except in certain cases such as live multimedia streaming. Developer time is important in use of software watermarks as the developer should not have to spend a large amount of time preparing a software watermark.

The complexity of a software watermark is proportional to the resilience of the watermark - that is, the greater amount of time a developer spends embedding a watermark the harder it may be for an adversary to crack.
