Abstract
Techniques are provided for dynamic configuration of search parameters for multimedia fingerprint databases that use weak bits. A multimedia fingerprint database, which stores reference fingerprints and uses weak bits, is maintained. Maintaining the database includes dynamically configuring one or more of the following parameters: a fingerprint length of those portions of the reference fingerprints that are used to identify multimedia objects; an index length of the index used to index those portions of the reference fingerprints that are used to identify multimedia objects; a threshold that is used to determine whether multimedia objects are correctly identified; and a number of the weak bits in the reference fingerprints.
