Adaptive and recursive filtering for sample submission

A computer readable medium comprising computer executable instructions stored thereon to cause one or more processing units to:

• identify a sample for submission to a server;
• receive an indication from the server whether sample is available to the server;
• and
• if the indication is that the sample is not available to the server:
• split the sample into a plurality of portions according to a set of rules;
• create hashes of each of the plurality of portions;
• submit the hashes of each of the plurality of portions and their respective locations to the server;
• receive an indication from the server whether each of the plurality of portions is available to the server;
• and
• submit to the server only those portions wherein the server indicated that the portion is not known to the server.

A computer readable medium comprising computer executable instructions stored thereon to cause one or more processing units to:

• send a set of sample splitting rules to a client;
• receive a hash of a sample from the client;
• determine whether the sample is available to a dictionary communicatively coupled to the one or more processing units;
• provide an indication to the client whether the sample is available;
• and
• if the indication is that the sample is not available:
• receive a plurality of hashes of portions of the sample and their respective locations from the client, wherein the portions have been created by splitting the sample according to the set of rules;
• determine whether each of the plurality of portions is available to the dictionary;
• provide an indication to the client whether each of the plurality of portions is available to the dictionary;
• receive from the client only those portions wherein the portion is not available to the dictionary;
• and
• storing the received portions in the dictionary.

A method of sample analysis, comprising:

• sending a set of sample splitting rules from a server to a client;
• receiving at the server a hash of a sample from the client;
• determining at the server whether the sample is available to a dictionary communicatively coupled to the server;
• providing by the server an indication to the client whether the sample is available to the server;
• and
• if the indication is that the sample is not available:
• receiving at the server a plurality of hashes of portions of the sample and their respective locations from the client, wherein the portions have been created by splitting the sample according to the set of rules;
• determining at the server whether each of the plurality of portions is available to the dictionary;
• providing by the server an indication to the client whether each of the plurality of portions is available to the dictionary;
• receiving at the server only those portions wherein the portion is not available to the dictionary;
• and
• storing the received portions in the dictionary.

An apparatus configured to perform sample analysis, comprising:

• a memory;
• and
• one or more processing units, communicatively coupled to the memory, wherein the memory stores instructions to configure the one or more processing units to:
• identify a sample for submission to a server;
• create a hash of the sample;
• submit the hash of the sample to the server;
• receive an indication from the server whether the sample is available to the server;
• and
• if the indication is that the sample is not available to the server:
• split the sample into a plurality of portions according to a set of rules;
• create hashes of each of the plurality of portions;
• submit the hashes of each of the plurality of portions and their respective locations to the server;
• receive an indication from the server whether each of the plurality of portions is available to the server;
• and
• submit to the server only those portions wherein the server indicated that the portion is not available to the server.
