Abstract
A secure data parser is provided that may be integrated into any suitable system for securely storing and communicating data. The secure data parser parses data and then splits the data into multiple portions that are stored or communicated distinctly. Encryption of the original data, the portions of data, or both may be employed for additional security. The secure data parser may be used to protect data in motion by splitting original data into portions of data, that may be communicated using multiple communications paths.
Claims24
A method for securing a data set, the method comprising:
- determining a number of data portions into which to distribute the data set;
- distributing, using a hardware processor, substantially equal shares of data from the data set into each of the data portions according to a splitting key, such that at least one of the data portions contains a different number of shares than a remainder of the data portions;
- appending redundancy data to each of the data portions;
- storing each of the data portions separately;
- and
- restoring the data set from a subset of the data portions.
A system for securing a data set, the system comprising:
- a hardware processor configured to:
- determine a number of data portions into which to distribute the data set;
- distribute substantially equal shares of data from the data set into each of the data portions according to a splitting key such that at least one of the data portions contains a different number of shares than a remainder of the data portions;
- append redundancy data to each of the data portions;
- restore the data set from a subset of the data portions;
- and
- two or more memories configured to store each of the data portions separately.
