Systems and methods to protect sensitive data at processing intermediaries
View Patent ↗A system, platform, program product, and/or method for protecting sensitive data including decrypting an incoming message comprising a base message and the sensitive electronic data; removing the sensitive electronic data from the incoming message to create a stripped message; encrypting the sensitive electronic data; storing the encrypted sensitive electronic data in In-Memory Cache; and permitting the stripped message to be further processed without the sensitive electronic data. The system, platform, program product and/or method in an embodiment further includes: retrieving from the In-Memory Cache the encrypted sensitive electronic data; decrypting the encrypted sensitive electronic data retrieved from the In-Memory Cache; and injecting the sensitive electronic data into the stripped message. In a further aspect the system, platform, program product and/or method further includes encrypting the outbound message with the sensitive electronic data and permitting the encrypted outbound message with the sensitive electronic data to reach an external computing system.
1 . A computer-implemented method for protecting sensitive electronic data, the method comprising:
decrypting an incoming message comprising a base message and the sensitive electronic data;
removing the sensitive electronic data from the incoming message to create a stripped message;
encrypting the sensitive electronic data removed from the incoming message;
storing the encrypted sensitive electronic data in In-Memory Cache; and
permitting the stripped message to be further processed without the sensitive electronic data.
2 . The method as recited in claim 1 , further comprising decrypting the incoming message with an Interceptor.
3 . The method recited in claim 2 , further comprising decrypting the incoming message using security keys exchanged with an external system that transmitted the incoming message.
4 . The method as recited in claim 1 , wherein the security keys are exchanged out of band with the incoming message.
5 . The method recited in claim 1 , further comprising storing the encrypted sensitive data in In-Memory Cache for a temporary time period that is at least one of a group consisting of: a fixed time period, a predefined time period, a predetermined time period, an adjustable time period, a programmable time period, and combinations thereof.
6 . The method as recited in claim 1 , wherein removing the sensitive electronic data from the incoming message comprises:
identifying sensitive electronic data to check for in the decrypted incoming message; and
checking the decrypted incoming message for the identified sensitive electronic data.
7 . The method as recited in claim 6 , further comprising using an attribute list to identify sensitive electronic data in the decrypted incoming messages.
8 . The method as recited in claim 7 , further comprising comparing the decrypted incoming message to sensitive electronic data identified in the attribute list.
9 . The method as recited in claim 7 , wherein the attribute list is a configurable JSON Attribute List where attributes can be at least one of a group consisting of an added attribute, a modified attribute, a removed attribute, and combinations thereof from the JSON Attribute List.
10 . The method as recited in claim 1 , wherein encrypting the sensitive electronic data comprises using a Hardware Security Module to encrypt the sensitive electronic data with an encryption key.
11 . The method as recited in claim 10 , further comprising supplying the encryption key by an external system that transmitted the incoming message.
12 . The method as recited in claim 1 , wherein an interceptor:
decrypts an incoming message comprising a base message and sensitive electronic data;
removes the sensitive electronic data from the incoming message to create a stripped message;
encrypts the sensitive electronic data;
stores the encrypted sensitive electronic data in In-Memory Cache; and
permits the stripped message to be further processed without the sensitive electronic data.
13 . The method as recited in claim 1 , further comprising invoking an intermediary computing system REST API.
14 . The method as recited in claim 1 , further comprising:
retrieving from the In-Memory Cache the encrypted sensitive electronic data;
decrypting the encrypted sensitive electronic data retrieved from the In-Memory Cache using a Hardware Security Module; and
injecting the sensitive electronic data into the stripped message.
15 . The method as recited in claim 1 , further comprising encrypting the outbound message with the sensitive electronic data and permitting the encrypted outbound message with the sensitive electronic data to reach an external computing system.
16 . The method as recited in claim 15 , wherein an inceptor encrypts the outbound message with a security key exchanged with an external system that transmitted the incoming message.
17 . The method as recited in claim 1 , further comprising an interceptor using a Hardware Security Module (HSM) to decrypt the encrypted sensitive electronic data retrieved from the In-Memory Cache.
18 . The method as recited in claim 14 , further comprising:
permitting the encrypted outbound message with the sensitive electronic data to reach an external computing system; and
permitting at least one of the stripped message without containing the sensitive electronic data or an enriched stripped message comprising the stripped message to be further processed but without containing the sensitive electronic data to reach a different external computing system.
19 . A computer program product for protecting sensitive electronic data, the computer program product comprising a non-transitory computer readable storage medium having program instructions embodied therewith, the program instructions executable by a processor to cause the processor to:
decrypt an incoming message comprising a base message and the sensitive electronic data;
remove the sensitive electronic data from the incoming message to form a stripped message;
encrypt the sensitive electronic data removed from the incoming message;
store the encrypted sensitive electronic data in In-Memory Cache; and
permit the stripped message to be further processed without the sensitive electronic data.
20 . The computer program product as recited in claim 19 , further comprising programming instructions that when executed by the processor cause the processor to:
retrieve from the In-Memory Cache the encrypted sensitive electronic data;
decrypt the encrypted sensitive electronic data retrieved from the In-Memory Cache using a Hardware Security Module (HSM);
inject the sensitive electronic data into the stripped message to form an outbound message with the electronic sensitive data;
encrypt the outbound message with the sensitive electronic data;
permit the encrypted outbound message with the sensitive electronic data to reach an external computing system; and
permit the base message that is further processed without the sensitive electronic data to reach the external computing system or a different external computing system.
