Abstract
A system is provided for selective data access management. The system comprises a content sharing module configured to share a complete digital content file with a recipient device; an encryption module configured to encrypt discrete byte streams within the digital content file based on designated access rules; and a decryption module on the recipient device configured to decrypt only the designated byte streams based on access rules, thereby enabling selective access to specific portions of the digital content file.
Claims20
A system for selective data access management, comprising:
- a content sharing module configured to share a complete digital content file with a recipient device;
- an encryption module configured to encrypt discrete byte streams within the digital content file based on designated access rules;
- and
- a decryption module on the recipient device configured to decrypt only the designated byte streams based on access rules, thereby enabling selective access to specific portions of the digital content file.
A method for managing selective access to digital content, comprising:
- encrypting a digital content file at the byte-stream level according to predefined access rules specifying one or more portions of the file accessible by a recipient;
- transmitting the encrypted digital content file to a recipient device;
- decrypting, at the recipient device, only the designated byte-stream portions based on the access rules;
- and
- restricting visibility of the remaining portions of the digital content file.
A system for location-based data rights management, comprising:
- a geofencing module configured to define access constraints based on geographic parameters including latitude, longitude, and relative altitude;
- an encryption module configured to encrypt digital content and associate access permissions with specific geographic locations;
- and
- a recipient device configured to decrypt the digital content only when located within the predefined geographic parameters.
