Method and apparatus for reducing duplicates of multimedia data items in service system

摘要

A method of reducing duplicates of multimedia data items in a service system includes maintaining service system hash values for the multimedia data items of the service system; receiving a first multimedia data item; and hashing the received multimedia data item to provide a first hash value. The method further includes searching the first hash value from the service system hash values; and approving the received multimedia data item to the service system in response to the first hash value being not found when searching from the service system hash values.

1. A method for reducing duplicates of multimedia data item of a service system, the method comprising:
maintaining, at a server apparatus, service system hash values for the multimedia data item of the service system; receiving, by the server apparatus, a first multimedia data item, wherein the first multimedia data item comprising still image data and metadata; hashing a block of the still image data to provide a first hash value; searching the first hash value from the service system hash values; approving the received multimedia data item to the service system in response to the first hash value being not found when searching from the service system hash values; triggering hashing of at least part of the metadata in response to the first hash value being found when searching from the service system hash values; hashing at least part of the metadata to provide a second hash value; searching the second hash value from the service system hash values; and rejecting the received multimedia data item from the service system in response to the first and the second hash value being found when searching from the service system hash values.
