Abstract

A data processing apparatus, a method and computer program product for comparing a first object associated with said data processing apparatus with a second object associated with a remote data processing apparatus, are provided. The data processing apparatus comprises an input device operable to accept a first and a second set of data associated with said first object. Said first set of data describes said first object, and said second set of data describes a third object. Additionally, the data processing apparatus includes a memory. Said memory is adapted to store said first and said second set of data. The data processing apparatus further comprises a receiver. Said receiver is adapted to obtain a first subset of a third and a fourth set of data, respectively, from said remote data processing apparatus. Said third and said fourth set of data is associated with said second object, and said third set of data describes said second object, and said fourth set of data describes a fourth object. It also includes a transmitter. Said transmitter is adapted to send a first subset of said first and said second set of data, respectively, to said remote data processing apparatus. Finally, the data processing apparatus comprises a processor. The processor is adapted to perform correlation analysis between said first subsets of said first and said fourth set of data, respectively, to obtain a first value of correlation between said first and said second object. The processor is further adapted to perform correlation analysis between said first subsets of said second and said third set of data, respectively, to obtain a second value of correlation between said first and said second object.

Dependent claims

A data processing apparatus for comparing a first object, associated with said data processing apparatus, with a second object, associated with a remote data processing apparatus, said data processing apparatus comprising:

an input device operable to accept a first and a second set of data associated with said first object, said first set of data describing said first object and said second set of data describing a third object;
a memory, wherein said memory is adapted to store said first and said second set of data;
a receiver, wherein said receiver is adapted to obtain a first subset of a third and a fourth set of data, respectively, from said remote data processing apparatus, said third and said fourth set of data being associated with said second object, said third set of data describing said second object and said fourth set of data describing a fourth object;
a transmitter, wherein said transmitter is adapted to send a first subset of said first and said second set of data, respectively, to said remote data processing apparatus;
and
a processor, wherein said processor is adapted to perform correlation analysis between said first subsets of said first and said fourth set of data, respectively, to obtain a first value of correlation between said first and said second object, and correlation analysis between said first subsets of said second and said third set of data, respectively, to obtain a second value of correlation between said first and said second object,
wherein said receiver further is adapted to obtain a second subset of said fourth set of data from said remote data processing apparatus,
wherein said transmitter further is adapted to send a second subset of said second set of data to said remote data processing apparatus, and
wherein, if said first value of correlation meets or exceeds a first threshold value and said second value of correlation meets or exceeds a second threshold value, said processor further is adapted to perform correlation analysis between a second subset of said first set of data and said second subset of said fourth set of data, to obtain a third value of correlation between said first and said second object, said third value of correlation indicating a similarity between said fourth and said first object.

A method of comparing a first object, associated with a data processing apparatus, with a second object, associated with a remote data processing apparatus, comprising:

inputting a first and a second set of data associated with said first object into said data processing apparatus, said first set of data describing said first object and said second set of data describing a third object;
storing said first and said second set of data in said data processing apparatus;
receiving a first subset of a third and a fourth set of data, respectively, from said remote data processing apparatus into said data processing apparatus, said third and said fourth set of data being associated with said second object, said third set of data describing said second object and said fourth set of data describing a fourth object;
transmitting a first subset of said first and said second set of data, respectively, to said remote data processing apparatus from said data processing apparatus;
performing, by means of said data processing apparatus, correlation analysis between said first subsets of said first and said fourth set of data, respectively, to obtain a first value of correlation between said first and said second object, and correlation analysis between said first subsets of said second and said third set of data, respectively, to obtain a second value of correlation between said first and said second object;
receiving a second subset of said fourth set of data from said remote data processing apparatus into said data processing apparatus;
transmitting a second subset of said second set of data to said remote data processing apparatus from said data processing apparatus;
and
if said first value of correlation meets or exceeds a first threshold value and said second value of correlation meets or exceeds a second threshold value, performing, by means of said data processing apparatus, correlation analysis between a second subset of said first set of data and said second subset of said fourth set of data, to obtain a third value of correlation between said first and said second object, said third value of correlation indicating a similarity between said fourth and said first object.
