Hong Kong scrapped fingerprinting children in schools last year as the Justice of the Peace at the Hong Kong Office of the Privacy Commissioner, Roderick Woo said it conflicted with their Data Protection Act he decided: "It was a contravention of our law, which is very similar to your law, which is that the function of the school is not to collect data in this manner, that it was excessive and that there was a less privacy-intrusive method to use."
PERSONAL DATA (PRIVACY) ORDINANCE
SCHEDULE 1 [s. 2(1) & (6)]
DATA PROTECTION PRINCIPLES
"the data are adequate but not excessive in relation to that purpose."
THE DATA PROTECTION PRINCIPLES
"Personal data shall be adequate, relevant and not excessive in relation to the purpose or purposes for which they are processed."
However we in the UK are still rolling out biometric systems in schools for fingerprinting and now iris scanning and our data protection act virtually reads the same in regard to excessive and adequate data held.
Do children really need to give up their biometrics for a library book or food? I'm with Roderick Woo on this one.
