Multi-party encryption cube processing apparatuses, methods and systems

Abstract

Computer-implemented systems and methods are disclosed herein for use within secure multi-party computation. A system and method are used for storing an operation preference and a cryptographic preference. A data set is stored based on the operation preference and the cryptographic preference. A determination is made that processing the query involves performing an allowable operation on the data set based on the operation preference.

         22 . A client system for use in database operations on data associated with multiple parties, the client system comprising:
 a memory; and   one or more processors for executing instructions stored in the memory to:
 transmit, to a data processing system, first data handling preferences associated with first transaction data stored in a database; 
 transmit, to the data processing system, a query associated with an attribute of the first transaction data; and 
 receive, from the data processing system, a summarized version of a transaction data analysis, wherein the transaction data analysis is based on:
 the attribute of the first transaction data; 
 second transaction data stored in the database, the second transaction data inaccessible to the client system; and 
 an allowable operation determined by the data processing system according to the first data handling preferences and second data handling preferences associated with the second transaction data, wherein the allowable operation is performed on the first transaction data and the second transaction data; and 
 wherein the summarized version of the transaction data analysis excludes the second transaction data.

         31 . The client system of  claim 27  wherein the allowable operation comprises the allowed join operation and the first encryption protocol. 
     
     
         32 . The client system of  claim 31 , wherein the first encryption protocol is a homomorphic-like method or Yao's algorithm. 
     
     
         33 . A method for use in database operations on data associated with multiple parties, the method comprising:
 providing, by a first user to a data processor, first data handling preferences associated with first transaction data stored in a database;   submitting, by the first user to the data processor, a query associated with an attribute of the first transaction data; and   receiving, by the first user from the data processor, a summarized version of a transaction data analysis, wherein the transaction data analysis is based on:
 sensitive data elements associated with the first transaction data and second transaction data, wherein the second transaction data is stored in the database, the second transaction data inaccessible to the first user; and 
 an allowable operation determined by the data processor according to the first data handling preferences and second data handling preferences associated with the second transaction data, wherein the allowable operation is performed on the sensitive data elements; and 
 wherein the summarized version of the transaction data analysis comprises results of the transaction data analysis without reporting sensitive data elements associated with the second transaction data. 
   
     
     
         34 . The method of  claim 33 , the method comprising providing, by the first user to the data processor, first data handling preferences associated with first transaction data stored in the database, wherein the first data handling preferences comprise at least one of a first operation preference or a first encryption protocol to be implemented on the first transaction data. 
     
     
         35 . The method of  claim 34 , wherein the allowable operation is performed with the first encryption protocol. 
     
     
         36 . The method of  claim 34 , wherein the second data handling preferences comprise at least one of a second operation preference or a second encryption protocol to be implemented on the second transaction data. 
     
     
         37 . The method of  claim 33 , wherein the second data handling preference was provided by a second user. 
     
     
         38 . The method of  claim 37 , wherein an identity of the second user is unknown to the first user. 
     
     
         39 . The method of  claim 34 , wherein providing, by the first user to the data processor, first data handling preferences comprises selecting the first data handling preferences from a list of data handling preferences provided by the data processor. 
     
     
         40 . The method of  claim 39 , wherein the list of data handling preferences comprises Yao's algorithm and a homomorphic-like method. 
     
     
         41 . The method of  claim 33 , wherein providing, by the first user to the data processor, first data handling preferences comprises supplying, by the first user to the data processor, an encryption method previously unavailable to the data processor.
