Abstract
Aspects of the present invention maintain data integrity of a monitored data object in a monitored storage repository. A first security value for the monitored data object is determined. The first security value is stored along with an authentic copy of the monitored data object in the secure repository. The second security value for the monitored data object is determined after a predetermined time interval. The first security value is compared with the second security value. An alert is generated in response to determining a difference between the second security value and the first security value.
Claims20
A method for maintaining data integrity of a monitored data object in a monitored storage repository, the method comprising the steps of:
- a computer determining a first security value for a monitored data object;
- the computer storing the first security value and a copy of the monitored data object in a secure repository;
- the computer determining a second security value for the monitored data object after a predetermined time interval;
- the computer comparing the second security value with the first security value;
- and
- the computer generating an alert in response to determining a difference between the second security value and the first security value.
A computer program product for maintaining data integrity of a monitored data object in a monitored storage repository, the computer program product comprising one or more computer-readable tangible storage devices and program instructions stored on at least one of the one or more computer-readable tangible storage devices, the program instructions comprising:
- first program instructions to determine a first security value for a monitored data object;
- second program instructions to store the first security value and a copy of the monitored data object in a secure repository;
- third program instructions to determine a second security value for the monitored data object after a predetermined time interval;
- fourth program instructions to compare the second security value with the first security value;
- and
- fifth program instructions to generate an alert in response to a determined difference between the second security value and the first security value.
A computer system for maintaining data integrity of a monitored data object in a monitored storage repository, the computer system comprising one or more processors, one or more computer-readable memories, one or more computer-readable tangible storage devices, and program instructions stored on at least one of the one or more storage devices for execution by at least one of the one or more processors via at least one of the one or more memories, the program instructions comprising:
- first program instructions to determine a first security value for a monitored data object;
- second program instructions to store the first security value and a copy of the monitored data object in a secure repository;
- third program instructions to determine a second security value for the monitored data object after a predetermined time interval;
- fourth program instructions to compare the second security value with the first security value;
- and
- fifth program instructions to generate an alert in response to a determined difference between the second security value and the first security value.
