| Research Abstract |
Digital fingerprinting is a technique for identifying malicious users when a digital content protected by copyright is illegally used. In this research, digital fingerprinting codes for multimedia were developed. In particular, when the number of malicious users is less than or equal to some pre-determined number, a number of new coding methods were developed so that the efficiency of the fingerprinting codes is improved and the codes can be implemented with low computational complexity.
