B Blinding

This appendix discusses the blinding functionality.

B.1 Blinding Logic

BIP Aggregate reports use blinded security (when needed) for users in Argus Safety. The V_USER_CASE_BLINDING view contains the blinded logic used in BIP reports. For more information, refer to the definition of this view in the Argus Safety database.

Along with the user's blinded access from Argus Safety, the BIP parameter Print Unblinded Data determines the contents to be printed in the report.

This parameter is applicable only if the user has access to view unblinded data; otherwise only blinded data is printed irrespective of the value of this parameter. Table B-1 explains this in detail.
