Cross-link

There's no downside to providing reasonable cross links, and several reasons for providing them. For example, effective cross-linking keeps visitors on your site longer (as opposed to heading off-site because they can't find what they need on your site."

(12)For the identification of cross-links between terrorism investigations and judicial proceedings against suspects of terrorist offences, reliable identification data is crucial. Due to the uncertainties regarding alphanumerical data especially for third country nationals, it should be possible to exchange biometric data. Due to the sensitive nature of biometric data and the impact processing of biometric data has on the respect for private and family life and the protection of personal data, as enshrined in Articles 7 and 8 of the Charter of Fundamental Rights of the European Union, a strict necessity test should be applied by the competent authorities and Eurojust in each case. (13)As information about existing cross-links to other judicial proceedings is most useful at an early stage of the investigation, it is necessary that the competent authorities provide information to Eurojust as soon as judicial authorities are involved. If the competent national authorities are already aware of cross-links, they should inform Eurojust accordingly.

Article 20 of the "General Data Protection Regulation” concerns immunity from automated profiling except under specified circumstances. It is conceivable that this may affect future applications of e.g. ANPRS systems (which already permit the automated and undetected identification of vehicles) combined with CCTV and face recognition software, especially if cross-linked to other individual data. (Presumably, no issues arise when the transport data are anonymised instead of cross-linked and cross-linked on a locational rather than an individual basis.) However, such cross-linking could conceivably be necessary in order to model and understand the behaviour of drivers and the extent to which it can be explained by other attributes, even if ‘measures’ such as personalised traffic management are not implemented.
