Abstract
A method for secure distribution of digital content (108), the method including the steps of dividing a unit of digital content into at least first and second portions (200), storing the first portion on a first computerized apparatus, digitally watermarking the second portion, and combining the first portion and the digitally watermarked second portion, thereby forming a watermarked (106) version of the digital content.

Apparatus for efficient and traceable distribution of digital content, the apparatus comprising:
- a content divider for dividing digital content into parts of a first kind and parts of a second kind,
- a first content part distributor for distributing parts of said first kind for easy access a content watermarked for inserting unique digital indicators into parts of said second kind per a request for said content, and
- a second content part distributor for distributing parts of said second kind per said request for association with parts of said first kind, thereby to distribute combined parts of said first and second kinds as reconstituted uniquely indicated digital content.
A method for secure distribution of digital content, the method comprising the steps of:
- dividing a unit of digital content into at least one portion of a first kind and at least one portion of a second kind;
- storing said at least one portion of a first kind on a first computerized apparatus;
- digitally watermarking said at least one portion of a second kind;
- storing said digitally watermarked portion of a second kind on a second computerized apparatus;
- and
- combining said portion of a first kind and said digitally watermarked portion of a second kind, thereby forming a watermarked version of said digital content.
A method for secure distribution of digital content, the method comprising the steps of:
- dividing a unit of digital content into at least portions of a first kind and portions of a second kind, wherein said portions of a first kind are larger than said portions of a second kind, and wherein said dividing step comprises at least one of:
- dividing said digital content such that a qualitative measure of either of said portions of said first kind and said portions of said second kind are degraded relative to a corresponding qualitative measure of said digital content, and
- dividing said digital content such that either of said portions of said first kind and portions of said second kinds are individually inoperable;
- storing said portion of said first kind on a first computerized apparatus;
- storing said portion of said second kind on a second computerized apparatus;
- and
- combining said portions of said first kind and said portions of said second kind, thereby recreating said digital content.
A system for secure distribution of digital content, the system comprising:
- a content divider for dividing a unit of digital content into at least portions of a first kind and portion of a second kind;
- a first storage device for storing said portions of a first kind on a first computerized apparatus;
- a watermarking unit for digitally watermarking said portions of a second kind;
- a second storage device for storing said digitally watermarked portions of a second kind on a second computerized apparatus;
- and
- a combiner for combining said portion of a first kinds and said digitally watermarked portion of a second kinds, thereby forming a watermarked version of said digital content.
A method for secure distribution of digital content, the method comprising the steps of:
- dividing a unit of digital content into at least portions of a first kind and portions of a second kind;
- storing said portion of a first kind on a computerized apparatus;
- storing said portion on a computerized apparatus;
- and
- combining said portion of a first kind and said portion of a second kind, thereby to form an operable version of said digital content.
