Abstract
A method of determining whether particular data is included in a data store. The particular data comprises a plurality of first data values and the data store comprises a plurality of second data values. The method comprises obtaining identification data associated with the particular data. The identification comprises a subset of said first data values. A portion of the data store is retrieved and it is determined whether at least a predetermined number of data values of the identification data have a predetermined relationship with corresponding second data values of the retrieved portion of the data store.
Claims38
A method of determining whether particular data is included in a data store comprising a plurality of second segments, wherein the particular data comprises a plurality of first data values, the data store comprises a plurality of second data values and the method comprises:
- obtaining identification data associated with said particular data, said identification data comprising a subset of said first data values;
- retrieving a portion of said data store, wherein said portion is one of said plurality of second segments;
- and
- determining whether at least a predetermined number of first data values of said identification data have a predetermined relationship with corresponding second data values of said retrieved portion of the data store, so as to determine whether the particular data is included in the data store.
A non-transitory computer readable medium carrying computer readable instructions arranged to control a computer to carry out a method for determining whether particular data is included in a data store comprising a plurality of second segments, wherein the particular data comprises a plurality of first data values, the data store comprises a plurality of second data values and the computer readable instructions comprise instructions controlling the computer to:
- obtain identification data associated with said particular data, said identification data comprising a subset of said first data values;
- retrieve a portion of said data store, wherein said portion is one of said plurality of second segments;
- and
- determine whether at least a predetermined number of data values of said identification data have a predetermined relationship with corresponding second data values of said retrieved portion of the data store.
Apparatus for determining whether particular data is included in a data store comprising a plurality of second segments, wherein the particular data comprises a plurality of first data values, and the data store comprises a plurality of second data values, the apparatus comprising:
- a memory storing processor readable instructions;
- and
- a processor configured to read and execute instructions stored in said memory;
- wherein said processor readable instructions comprise instructions configured to control the processor to:
- obtain identification data associated with said particular data, said identification data comprising a subset of said first data values;
- retrieve a portion of said data store, wherein said portion is one of said plurality of second segments;
- and
- determine whether at least a predetermined number of data values of said identification data have a predetermined relationship with corresponding second data values of said retrieved portion of the data store.
A method of determining whether particular data is included in a data store, wherein the particular data comprises a plurality of first data values arranged in a plurality of first segments, the data store comprises a plurality of second data values arranged in a plurality of second segments and the method comprises:
- obtaining identification data associated with said particular data, said identification data comprising first data values taken from one of said first segments;
- retrieving one of said second segments from said data store;
- determining whether at least a predetermined number of first data values of said identification data have a predetermined relationship with corresponding second data values of said retrieved second segment, so as to determine whether the particular data is included in the data store.
A non-transitory computer readable medium carrying computer readable instructions arranged to control a computer to carry out a method for determining whether particular data is included in a data store, wherein the particular data comprises a plurality of first data values arranged in a plurality of first segments, the data store comprises a plurality of second data values arranged in a plurality of second segments and the method comprises and the computer readable instructions comprise instructions controlling the computer to:
- obtain identification data associated with said particular data, said identification data comprising data values taken from one of said first segments;
- retrieve one of said second segments from said data store;
- and
- determine whether at least a predetermined number of data values of said identification data have a predetermined relationship with corresponding second data values of said retrieved second segment.
Apparatus for determining whether particular data is included in a data store, wherein the particular data comprises a plurality of first data values arranged in a plurality of first segments, and the data store comprises a plurality of second data values arranged in a plurality of second segments, the apparatus comprising:
- a memory storing processor readable instructions;
- and
- a processor configured to read and execute instructions stored in said memory;
- wherein said processor readable instructions comprise instructions configured to control the processor to:
- obtain identification data associated with said particular data, said identification data comprising data values taken from one of said first segments;
- retrieve one of said second segments from said data store;
- and
- determine whether at least a predetermined number of data values of said identification data have a predetermined relationship with corresponding second data values of said retrieved second segment.
