SECURED DATA COMMUNICATION IN A NETWORKED COMPUTER SYSTEM FOR PROVIDING OPTICAL LENSES

摘要

The invention relates to the supply of an optical lens adapted to a wearer comprising the steps of: a) receiving directly or indirectly via a manufacturing side from a first networked computer entity (PC1; PC3) located at a lens ordering side (LOS) a first set of data (S1) the first set of data (S1) comprising at least wearer s data and in particular wearer s prescription data b) sending a second set of data (S2) comprising at least an optical lens design information and the wearer s prescription data to a second networked computer entity (PC2) located at a lens designing side (LDS) and receiving from the second networked computer entity (PC2) a third set of data (S3) comprising at least optical lens data (OLD) calculated from the second set (S2) and c) sending at least to a third networked computer entity (PC3) at a lens manufacturing side (LMS) a fourth set of data (S4) comprising at least a part of the optical lens data (OLD) the at least optical lens data (OLD) of the fourth set of data (S4) being at least partially modified by a masking function (ENCR).
