My Lords, I thank the noble Lord, Lord Clement-Jones, for engaging constructively on this subject since we discussed it in Committee. I know that he is keen for data controllers to have clarity on the circumstances in which the processing of biometric data would be lawful. I recognise that the points he makes are of the moment: my department is aware of these issues and will keep an eye on them, even though we do not want to accept his amendments today.
To reiterate some of the points I made in my letter so generously quoted by the noble Lord, the GDPR regards biometric data as a “special category” of data due to its sensitivity. In order to process such data, a data controller must satisfy a processing condition in
Article 9 of the GDPR. The most straightforward route to ensure that processing of such data is lawful is to seek the explicit consent of the data subject. However, the GDPR acknowledges that there might be occasions where consent is not possible. Schedule 1 to the Bill makes provision for a range of issues of substantial public interest: for example, paragraph 8, which permits processing such as the prevention or detection of an unlawful act. My letter to noble Lords following day two in Committee went into more detail on this point.
The noble Lord covered much of what I am going to say about businesses such as banks making use of biometric identification verification mechanisms. Generally speaking, such mechanisms are offered as an alternative to more conventional forms of access, such as use of passwords, and service providers should have no difficulty in seeking the data subject’s free and informed consent, but I take the point that obtaining proper, GDPR-compliant consent is more difficult when, for example, the controller is the data subject’s employer. I have considered this issue carefully following our discussion in Committee, but I remain of the view that there is not yet a compelling case to add new exemptions for controllers who wish to process sensitive biometric data without the consent of data subjects. The Bill and the GDPR make consent pre-eminent wherever possible. If that means employers who wish to install biometric systems have to ensure that they also offer a reasonable alternative to those who do not want their biometric data to be held on file, then so be it.
There is legislative precedent for this principle. Section 26 of the Protection of Freedoms Act 2012 requires state schools to seek parental consent before processing biometric data and to provide a reasonable alternative mechanism if consent is not given or is withdrawn. I might refer the noble Lord to any number of speeches given by members of his own party—the noble Baroness, Lady Hamwee, for example—on the importance of those provisions. After all, imposing a legislative requirement for consent was a 2010 Liberal Democrat manifesto commitment. The GDPR merely extends that principle to bodies other than schools. The noble Lord might respond that his amendment’s proposed subsection (1) is intended to permit processing only in a tight set of circumstances where processing of biometric data is undertaken out of necessity. To which I would ask: when is it genuinely necessary to secure premises or authenticate individuals using biometrics, rather than just cheaper or more convenient?
We also have very significant concerns with the noble Lord’s subsections (4) and (5), which seek to drive a coach and horses through fundamental provisions of the GDPR—purpose limitation and storage limitation, in particular. The GDPR does not in fact allow member states to derogate from article 5(1)(e), so subsection (5) would represent a clear breach of European law.
For completeness, I should also mention concerns raised about whether researchers involved in improving the reliability of ID verification mechanisms would be permitted to carry on their work under the GDPR and the Bill. I reassure noble Lords, as I did in Committee, that article 89(1) of the GDPR provides that processing of special categories of data is permitted for scientific research purposes, providing appropriate technical and organisational safeguards are put in place to keep the
data safe. Article 89(1) is supplemented by the safeguards in Clause 18 of the Bill. Whatever your opinion of recitals and their ultimate resting place, recital 159 is clear that the term “scientific research” should be interpreted,
“in a broad manner including for example technological development and demonstration”.
This is a fast-moving area where the use of such technology is likely to increase over the next few years, so I take the point of the noble Lord, Lord Clement-Jones, that this is an area that needs to be watched. That is partly why Clause 9(6) provides a delegated power to add further processing conditions in the substantial public interest if new technologies, or applications of existing technologies, emerge. That would allow us to make any changes that are needed in the future, following further consultation with the parties that are likely to be affected by the proposals, both data controllers and, importantly, data subjects whose sensitive personal data is at stake. For those reasons, I hope the noble Lord is persuaded that there are good reasons for not proceeding with his amendment at the moment.
The noble Baroness, Lady Hamwee, asked about behavioural issues. I had hoped that I might get some inspiration, but I fear I have not, so I will get back to her and explain all about behavioural characteristics.
