System and method for secure database management

A method comprising:

• receiving a request from a user device;
• encrypting the request to generate an encrypted request;
• searching a plurality of encrypted data items stored in a data storage system based on the encrypted request to identify a plurality of desired encrypted data items;
• in response to determining that two or more encrypted data items of the plurality of desired encrypted data items have a same interaction identification:
• locking the two or more encrypted data items;
• masking the two or more encrypted data items;
• and
• removing the masked two or more encrypted data items from the plurality of desired encrypted data items;
• retrieving the plurality of desired encrypted data items from the data storage system;
• determining one or more algebraic operations based on the encrypted request;
• determining an encrypted response based on the encrypted request and the plurality of desired encrypted data items by performing the one or more algebraic operations on the plurality of desired encrypted data items;
• decrypting the encrypted response to obtain a decrypted response;
• determining an error for the decrypted response due to the one or more algebraic operations performed on the plurality of desired encrypted data items;
• and
• in response to determining that the error is less than an error threshold, sending the decrypted response to the user device.

A non-transitory computer-readable medium storing instructions that, when executed by one or more processors, cause the one or more processors to:

• receive a request from a user device;
• encrypt the request to generate an encrypted request;
• search a plurality of encrypted data items stored in a data storage system based on the encrypted request to identify a plurality of desired encrypted data items;
• in response to determining that two or more encrypted data items of the plurality of desired encrypted data items have a same interaction identification:
• lock the two or more encrypted data items;
• mask the two or more encrypted data items;
• and
• remove the masked two or more encrypted data items from the plurality of desired encrypted data items;
• retrieve the plurality of desired encrypted data items from the data storage system;
• determine one or more algebraic operations based on the encrypted request;
• determine an encrypted response based on the encrypted request and the plurality of desired encrypted data items by performing the one or more algebraic operations on the plurality of desired encrypted data items;
• decrypt the encrypted response to obtain a decrypted response;
• determine an error for the decrypted response due to the one or more algebraic operations performed on the plurality of desired encrypted data items;
• and
• in response to determining that the error is less than an error threshold, send the decrypted response to the user device.
