Abstract
An approach for generating updated error detecting code for a partial update of data is disclosed. The techniques include receiving data representing a change to a portion of a data object, the data object having a first error detecting code, and the portion of the data object having an offset from the beginning of the data object; generating a combination term by combining the data and the portion of the data object; and computing a second error detecting code based on the combination term. The techniques may further include computing a third error detecting code by combining the first error detecting code and the second error detecting code, the third error detecting code being configured to detect an error in the data object as changed by the data, and storing the data and the third error detecting code.
