Data Signal with a Database and a Compressed Key
First Claim
Patent Images
1. A content provider, comprising:
- a database comprised of encrypted content;
a compressed key generator that generates a compressed key from which a first key can be derived to gain access to a first data subset of the database, and a second key can be derived to gain access to a second data subset of the database.

5. A computer-readable medium having stored thereon a data structure comprising:
-
a first field containing an encrypted database;
a second field containing a compressed key from which a first key can be derived to gain access to a first data subset of the database, and a second key can be derived to gain access to a second data subset of the database;
a third field functioning to delimit the end of the data structure. - View Dependent Claims (6)

7. A computer data signal embodied on one or more computer-readable media, comprising:
-
a code segment including instructions for generating an encrypted database embodied on a computer-readable media, the database having a first data subset and a second data subset;
a code segment including instructions for generating a compressed key from which a first key can be derived to gain access to the first data subset, and a second key can be derived to gain access to the second data subset. - View Dependent Claims (8)
