Computer system linked by using information in data objects
First Claim
1. A system for operating on watermarked data that represents a creative work, said system comprising:
- a first computer having a first memory storing data representing a plurality of creator identifiers and creator contact data corresponding to each of the creator identifiers;
a second computer programmed to read a watermark in the digital data to reveal one of the plurality of creator identifiers;
a network for communicating the revealed one of the plurality of creator identifiers to said first computer to obtain the creator contact data corresponding to the one of the plurality of creator identifiers from said first memory.

Abstract
Various improvements to steganographic systems, and applications therefore, are disclosed. The improvements include facilitating scale and rotation registration for steganographic decoding by use of rotationally symmetric steganographically embedded patterns and subliminal digital graticules; improved techniques for decoding without access to unencoded originals; improving robustness of steganographic coding in motion pictures and/or in the presence of lossy compression/decompression; and representing data by patterned bit cells whose energy in the spatial domain facilitates decoding registration. Applications include enhanced-security financial transactions, counterfeit resistant identification cards, fraud deterrent systems for cellular telephony, covert modem channels in video transmissions, photo duplication kiosks with automatic copyright detection, and hotlinked image objects (e.g. with embedded URLs) for use on the internet.
