Porcupine Web Application Server
It’s a web application server written in python language. It is open source software. One of the main purposes of Porcupine is that it is used for watermark of the digital images. Using this you can either include a visible watermark in the documents or can include any information with the help of a secret password. Here the information can be encrypted. The validation of the host and the true identity of the legal host are ensured by this server. If there is increased number of host signals then it filters them and chooses the legal owner and represents that. Porcupine surely safeguards the privacy of the legal owner and also inhibits illegal host claims. The server provides a safer way of distribution over the internet. The watermark can have a group of bits which has the information about the signal or the author.
