Secure probabilistic analytics using an encrypted analytics matrix

A system for building an analytic matrix, comprising:

• a processor;
• and
• a memory for storing instructions, the processor executing the instructions to:
• determine an analytic and at least one parameter associated with the analytic;
• extract, using a term generation function, a set of term elements from the analytic and the at least one analytic parameter;
• generate, using a keyed hash function, a set of hashes from the set of term elements;
• partition elements of the set of hashes to generate a set of vectors, with each vector of the set of vectors having a pre-defined dimension;
• determine whether for at least one matrix element associated with row j and column m of at least one analytic matrix, there is a vector C from the set of vectors wherein C[j]=m;
• assign the at least one matrix element a non-zero value when a result of the determination is positive;
• and
• assign the at least one matrix element a zero value when the result of the determination is negative.

A non-transitory computer-readable storage medium having embodied thereon instructions, which when executed by at least one processor, perform steps of a method, the method comprising:

• determining an analytic and at least one parameter associated with the analytic;
• extracting, using a term generation function, a set of term elements from the analytic and the at least one analytic parameter;
• generating, using a keyed hash function, a set of hashes from the set of term elements;
• partitioning elements of the set of hashes to generate a set of vectors, with each of vector of the set of vectors having a pre-defined dimension;
• determining whether for at least one matrix element associated with row j and column m of at least one analytic matrix, there is a vector C from the set of vectors wherein C[j]=m;
• assigning the at least one matrix element a non-zero value when a result of the determination is positive;
• and
• assigning the at least one matrix element a zero value when the result of the determination is negative.
