Abstract

A content identification method and system, and a secure content identification mechanism (SCIDM) client and server are provided. The content identification method includes: selecting an identification mechanism for a content to be identified; extracting identification information of the content to be identified corresponding to the selected identification mechanism; and sending a first content identification request, in which the first content identification request contains the selected identification mechanism and the identification information, and is adapted to request an SCIDM server to identify an attribute of the content to be identified by using the identification mechanism and according to the identification information. Thus, a load of a content identification system is reduced, and an efficiency of content identification is improved.

Dependent claims

A content identification method, comprising:

selecting, by a secure content identification mechanism (SCIDM) client, a first identification mechanism for a content to be identified;
extracting first identification information of the content corresponding to the first identification mechanism selected by the SCIDM client;
sending a first content identification request by the SCIDM client, wherein the first content identification request comprises the first identification mechanism and the first identification information, and wherein the first content identification request requests an SCIDM server to search content data stored in the SCIDM server for the first identification information by using the first identification mechanism and to send an attribute of the content when the SCIDM server determines that the first identification information matches the content data stored in the SCIDM server;
and
when the SCIDM server determines that the first identification information does not match the content data stored in the SCIDM server, selecting, by the SCIDM client, a second identification mechanism for the content to be identified, extracting second identification information of the content corresponding to the second identification mechanism, and sending the second identification mechanism and the second identification information to the SCIDM server to request the SCIDM server to search the content data stored in the SCIDM server for the second identification information by using the second identification mechanism,
wherein selecting the first identification mechanism or selecting the second identification mechanism comprises selecting the identification mechanism for the content to be identified based at least in part on a load condition of a content identification system,
wherein a simple content identification mechanism is selected when the content identification system is under a low load, and
wherein a complex content identification mechanism is selected when the content identification system is under a high load.

5 more elements

A secure content identification mechanism (SCIDM) client, comprising:

a processor;
and
a computer-readable medium for storing program codes, which, when executed by the processor, cause the processor to:
select a first identification mechanism for a content to be identified;
extract first identification information of the content to be identified corresponding to the first identification mechanism;
send a first content identification request, wherein the first content identification request comprises the first identification mechanism and the first identification information, and wherein the first content identification request requests an SCIDM server to search content data stored in the SCIDM server for the first identification information by using the first identification mechanism and send an attribute of the content when the SCIDM server determines that the first identification information matches the content data stored in the SCIDM server;
and
when the SCIDM server determines that the first identification information does not match the content data stored in the SCIDM server, select a second identification mechanism for the content to be identified, extract second identification information of the content corresponding to the second identification mechanism, and send the second identification mechanism and the second identification information to the SCIDM server to request the SCIDM server to search the content data stored in the SCIDM server for the second identification information by using the second identification mechanism,
wherein the first identification mechanism or the second identification mechanism is selected based at least in part on a load condition of a content identification system,
wherein a simple content identification mechanism is selected when the content identification system is under a low load, and
wherein a complex content identification mechanism is selected when the content identification system is under a high load.

8 more elements

A secure content identification mechanism (SCIDM) server, comprising:

a processor;
and
a computer-readable medium for storing program codes, which, when executed by the processor, cause the processor to:
receive a first content identification request comprising a plurality of identification mechanisms sent by an SCIDM client;
acquire a first identification mechanism, first identification information corresponding to the first identification mechanism, a second identification mechanism, and second identification information corresponding to the second identification mechanism comprised in the first content identification request;
search content data stored in the SCIDM server for the first identification information by using the first identification mechanism;
send an attribute of the content when the SCIDM server determines that the first identification information matches the content data stored in the SCIDM server;
and
search the content data stored in the SCIDM for the second identification information by using the second identification mechanism when the SCIDM server determines that the first identification information does not match the content data stored in the SCIDM server,
wherein the first identification mechanism or the second identification mechanism is selected based at least in part on a load condition of a content identification system,
wherein a simple content identification mechanism is selected when the content identification system is under a low load, and
wherein a complex content identification mechanism is selected when the content identification system is under a high load.

9 more elements

A content identification method, comprising:

selecting, by a secure content identification mechanism (SCIDM) client, a first identification mechanism and a second identification mechanism for a content to be identified;
extracting first identification information of the content corresponding to the first identification mechanism and second identification information of the content corresponding to the second identification mechanism selected by the SCIDM client;
and
sending a content identification request by the SCIDM client, wherein the content identification request comprises the first identification mechanism, the first identification information, the second identification mechanism, and the second identification information, and wherein the content identification request requests an SCIDM server to search content data stored in the SCIDM server for the first identification information by using the first identification mechanism, send an attribute of the content when the SCIDM server determines that the first identification information matches the content data stored in the SCIDM server, and search the content data in the SCIDM server for the second identification information by using the second identification mechanism when the SCIDM server determines that the first identification information does not match the content data stored in the SCIDM server,
wherein selecting the first identification mechanism or selecting the second identification mechanism comprises selecting the identification mechanism for the content to be identified based at least in part on a load condition of a content identification system,
wherein a simple content identification mechanism is selected when the content identification system is under a low load, and
wherein a complex content identification mechanism is selected when the content identification system is under a high load.
