Description

The user can be identified by providing the IP-address. Including the full IP-address in the description of a usage event is not permitted by international privacy laws. For this reason, the IP-address needs to be obfuscated. The IP-address must be hashed using MD5 encryption. MD5 encryption of IP addresses can easily be hacked. The question if such MD5 encryption secures the privacy sufficiently warrant further research by legal advisors.

XPath

Usage

Mandatory

Format

A data-URI, consisting of the prefix "data:", followed by a 32-digit hexadecimal number.

Example

data:c06f0464f37249a0a9f848d4b823ef2a

Note

The IP address of the requester is pseudonymised using encryptions, before it is exchanged and taken outside the web-server to another location. Therefore individual users can be recognised when aggregated from distributed repositories, but cannot be referred back to a 'natural person'. This method may seem consisted with the European Act for Protection of Personal data. The summary can be found here: ?http://europa.eu/legislation_summaries/information_society/l14012_en.htm. Further legal research needs to be done if this method is sufficient to protect the personal data of a 'natural person', in order to operate within the boundaries of the law.
