Definitions

  • This invention is to be used in area of software copyright protection.
  • Patent numbers for examples of this level of technology in International Patent Classification are the following: H04L9/00, G06F12/14, G06F17/60.
  • the main point of active digital watermarks is in the process of watermarking image of an executable stored in RAM during program run-time instead of watermarking the file itself. This is achieved by including additional code which alters the application code stored in RAM during application run-time.
  • the advantage of the active digital watermarks is in the fact that they are created during the run-time of application, not during its creation. Thus watermarks can contain any data relevant at the given moment, and this makes them an invaluable source of information.
  • application is being cracked by saving the RAM image of an executable, watermarks are saved as well.
  • the main difference of active digital watermarks from the passive digital watermarks is that they appear only if the software protection is being hacked (scheme 2).
  • table containing information about them is created (this information includes location of blocks in protected module, their size, type of data etc.).
  • Second phase is filling known blocks with data during program run-time. Any valuable information may be stored. Most valuable information for finding cracker includes: computer IP address, hardware and operation system details and information on current copy of software.
  • the third phase is search for watermarks in cracked program module and further extracting of information contained in these watermarks. Tables saved earlier are used to determine watermarks location in cracked module. If tables were not used, watermarks addresses are to be found manually after cracked module analysis in order to locate addresses of integrated code functions.
  • Active digital watermarks may be used to obtain information about the computer used for cracking software product. This information may include hardware, software and other details and may then be used by law institutes in investigating cases of software copyright violation.
  • activation session data (activation time, IP address, activation details etc.) is stored on activation server. Then this data is compared with data from watermarks in cracked software (IP address, software copy details, hardware details and operation system details) in order to determine personality of cracker.

Abstract

L'invention concerne une protection de droit d'auteur et de copie de logiciel, plus précisément, le filigranage de logiciel qui permet de suivre la source d'une copie illégale. Actuellement, il existe des procédés de chiffrement de fichiers en vue d'interdire l'exécution illégale d'un logiciel. La façon traditionnelle de craquer cette protection consiste légalement à exécuter un logiciel avec l'image de travail de sauvegarde d'un exécutable à partir d'une mémoire vive. L'image sauvegardée renferme un code entièrement ou partiellement déchiffré et elle est plus facile à craquer que le fichier d'origine. Le but de cette invention consiste à incorporer un code exécutable qui gère le filigranage numérique dans l'image de mémoire vive mentionnée, au lieu de mettre en filigrane numérique un fichier exécutable. Dans ce cas, la version craquée (sauvegardée à partir de la mémoire vive) contient des filigranes et elle constitue une source inestimable d'informations concernant l'origine du logiciel distribué illégalement, étant donné que ces filigranes peuvent contenir des informations sur le logiciel du système qui a été craqué.
