20110026709 | SYSTEM AND METHODS FOR PERMITTING OPEN ACCESS TO DATA OBJECTS AND FOR SECURING DATA WITHIN THE DATA OBJECTS - A system and methods for permitting open access to data objects and for securing data within the data objects is disclosed. According to one embodiment of the present invention, a method for securing a data object is disclosed. According to one embodiment of the present invention, a method for securing a data object is disclosed. The method includes the steps of (1) providing a data object comprising digital data and file format information; (2) embedding independent data into a data object; and (3) scrambling the data object to degrade the data object to a predetermined signal quality level. The steps of embedding and scrambling may be performed until a predetermined condition is met. The method may also include the steps of descrambling the data object to upgrade the data object to a predetermined signal quality level, and decoding the embedded independent data. The additional steps of descrambling and decoding may be performed until a predetermined condition is met. The predetermined condition may include, for example, reaching a desired signal quality of the data object. | 2011-02-03 |
20110026710 | System and Method for Cryptographically Authenticating Data Items - A cryptographic authentication system comprises an authentication media key block that comprises media key precursors. The system generates transformed keys by applying a function to a media ID of a media and each of the media key precursors, and generates entries in a binding table by applying an encrypting function to a media key of an encrypted content and each of the transformed keys. To play encrypted content, a media player processes the authentication media key block using a device key to extract a media key precursor, extracts a media key from the binding table using the extracted media key precursor and the media ID, and verifies that the extracted media key matches the media key of the encrypted content, allowing the media device to decrypt and play the encrypted content. | 2011-02-03 |
20110026711 | Asymmetric cryptography using shadow numbers - A method and an apparatus for enciphering and deciphering content with symmetric and asymmetric cryptography with the use of the shadow numbering system where two or more shadow values are used with two or more base values with a two side equation, on one side the value to encipher is multiplied with one of the shadow value then the modulus taken with the base value, to decipher the enciphered value is multiplied with the shadow value that didn't take part of the first equation then the modulus is taken with the base value, thus, deciphering the enciphered value. | 2011-02-03 |
