  • Read-only security protection
    Patent number: 12039059
    Abstract: The present disclosure involves systems, software, and computer implemented methods for read-only security protection. One example method includes receiving, from a client device, an on-change request to change an editable leading field from a first editable leading field value to a second editable leading field value. The editable leading field is referenced in an on-change rule. The on-change request includes a first security key and the client device is not allowed to modify the read-only target field. The on-change rule is executed to change the read-only target field from a first read-only target field value to a second read-only target field value based on the second editable leading field value. A second security key is generated based on at least the second read-only target field value and provided to the client device in response to the on-change request.
