Computer-implemented system and method for individual message encryption using a unique key
View Patent ↗A computer-implemented system and method for individual record encryption is provided. A plurality of records associated with incoming calls to a call center are maintained. A unique encryption key is randomly generated for each record. The records are each encrypted using the encryption key generated for that record. The keys are stored in a location separate from the encrypted records.
1. A computer-implemented system for individual record encryption, comprising:
a telephonic device to transmit a call to a call center; and
a server comprising a central processing unit, memory, an input port to receive records associated with the call incoming from the telephonic device, and an output port, the central processing unit configured to:
randomly generate for each of the records of the call a unique encryption key by receiving seed information for the unique encryption key for one such record of the call to be encrypted, obtaining a key counter unique to the one such record, and combining the seed information and unique key counter as the unique encryption key for the one such record of the call;
uniquely encrypt the records using the encryption key generated for that record;
associate each such encrypted record of the call and the unique encryption key for that encrypted record with an identification code; and
store the unique encryption keys with their associated identification codes in a location separate from the encrypted records that are also stored with the associated identification codes.
2. A system according to claim 1 , wherein the seed information comprises entropy from two or more servers and the key counter is one of selected by an agent and incremented by a number of two or more from a previous key counter.
3. A system according to claim 1 , wherein time is encrypted with the unique encryption key.
4. A system according to claim 3 , wherein the time comprises one of a time the incoming call was received, a time the incoming call was handled, and a time at which the incoming call was completed.
5. A system according to claim 1 , further comprising:
a counter module to increase the key counter during at least one of after every record and after every n records.
6. A system according to claim 1 , further comprising:
a compression module to compress one or more of the records prior to encryption.
7. A system according to claim 1 , further comprising:
a decryption module to decrypt at least one of the encrypted records, comprising:
an identification module to determine an identification code assigned to the encrypted record; and
a location module to locate the unique encryption key used to encrypt the encrypted record via the identification code.
8. A system according to claim 7 , wherein the encryption module encrypts the decrypted record using a different unique 10 encryption key.
9. A system according to claim 1 , wherein the records each comprise one of text, voice, and images.
10. A computer-implemented method for individual record encryption, comprising:
receiving a call into a call center via at least one telephonic device;
generating via a server a record for each of the incoming calls, wherein the server comprises a central processing unit, memory, an input port to receive the call incoming from the telephonic device, and an output port;
randomly generating for each of the records a unique encryption key, comprising:
receiving seed information for the unique encryption key for one such record to be encrypted;
obtaining a key counter unique to the one such record of the call; and
combining the seed information and unique key counter as the unique encryption key for the one such record of the call;
uniquely encrypting the records using the unique encryption key generated for that record;
associating each such encrypted record of the call and the unique encryption key for that encrypted record with an identification code; and
storing the unique encryption keys with the associated identification codes in a location separate from the encrypted records that are also stored with the associated identification codes.
11. A method according to claim 10 , further comprising:
obtaining the seed information from two or more servers;
receiving the key counter that is one of selected by an agent and incremented by a number of two or more from a previous key counter.
12. A method according to claim 10 further comprising: encrypting at least one of the key content and time with the unique encryption key.
13. A method according to claim 12 , wherein the time comprises one of a time the associated incoming call was received, a time the incoming call was handled, and a time at which the incoming call was completed.
14. A method according to claim 10 , further comprising:
increasing the key counter during at least one of after every record and after every n records.
15. A method according to claim 10 , further comprising:
compressing one or more of the records prior to encryption.
16. A method according to claim 10 , further comprising:
decrypting at least one of the encrypted records, comprising:
determining an identification code assigned to the encrypted record; and
locating the unique encryption key used to encrypt the encrypted record via the identification code.
17. A method according to claim 16 , further comprising:
encrypting the decrypted record using a different unique encryption key.
18. A method according to claim 10 , wherein the records each comprise one of text, voice, and images.
