Mappings defined on a Cartesian power of a finite set with the property to be identified on a subset of co-domain coordinates are considered. A mapping enlargement preserving the identification property is suggested. In the secret sharing schemes based on involutions, the result can be applied to specify authorized subsets when a new patticipant is added.
