Abstract:

Systems, methods, and software can be used to secure storage of personally identifiable information. In some aspects, a method includes receiving, by at least one hardware processor, a request to store a data record, wherein the data record comprises personally identifiable information for a person; dividing, by the at least one hardware processor, the data record into at least two data entries, each of the at least two data entry comprising a respective portion of the personally identifiable information; selecting, by the at least one hardware processor, a database cell for each of the at least two data entries to store the respective portion of the personally identifiable information, wherein the database cells for different data entries are in different database tables, different database rows, or different database columns; and storing, by the at least one hardware processor, the at least two data entries in the selected database cells.
