Abstract: The invention relates to a system and method providing access of one or more heterogeneous digital contents to at least one online Digital Rights Management (DRM) user by a DRM server. This invention involves receiving digital contents from the publishers and those digital contents are encrypted and user rights are granted to access the contents by the publisher. The DRM server stores the decryption information, user rights and user information in a repository. After authenticating the user who is connected with the DRM server through a DRM client, the DRM server sends a license to the DRM user which includes the decryption information and the user rights. The DRM client decrypts the contents based on the license information in the memory of the user's computer device and thus the content and the license are not locally stored.

Abstract: The technologies relate to a system and method for electronic signature agnostic verification. The method involves receiving a request to verify an electronic signature, thereafter validating an integrity of the electronic signature on the basis of one or more predefined validation parameters and validation fields, then analyzing the validated electronic signature to obtain one or more features of the validated electronic signature, further decoding the analyzed electronic signature using one or more decode parameters, and finally comparing the decoded electronic signature with a predefined value received from one or more sources, to check the correctness of the decoded electronic signature. The technique supports various electronic signature formats and electronic signature standards.

Abstract: The technique relates to a method for defending static and dynamic reverse engineering of software license control and devices thereof. To defend static reverse engineering of software license control the licensed application is wrapped with encryption wrapper, wherein the encryption wrapper encrypts the application with a first password. Then, at the time of executing the application, a password prompt is generated. Upon receiving the first password the application is decrypted. At the time of closing the application after execution, another password prompt is generated to create the second password and then the application is re-encrypted with the second password. To defend dynamic reverse engineering of software license control one or more licensing conditions of the licensed application is tested based on control file information, a random number generation or verification point rules. If any license condition violation is detected during testing then the application gets auto-locked by applying self-encryption technique.

Abstract: The invention relates to a system and method providing access of one or more heterogeneous digital contents to at least one offline Digital Rights Management (DRM) user by a DRM server. This invention involves establishing the trust relationship among the DRM server, DRM client, user's machine and the end user by means of digital certificate. The server generates protected digital content by means of using a standard encryption algorithm. The invention further involves determining whether a license for accessing the protected file is requested by the legitimate user, and if so, generating a license consisting the user rights and the protected decryption key to be downloaded by legitimate user. The DRM client decrypts the protected file using a decryption key of the license, and renders the content to the end user by calling the appropriate and customized viewer during consumption.
