The data processing agreement
You engage only processors that provide sufficient guarantees [1]. The agreement provides, among other things, that the supplier processes the data only on your documented instructions, including with regard to transfers to a country outside the EU [2], and it is set out in writing or in electronic form [3]. Ask where the data is processed: a transfer outside the EU is allowed only under the conditions of the GDPR [4].
What a provider of high-risk AI supplies
A high-risk system comes with instructions for use containing concise, complete, correct and clear information [5], including the intended purpose and the level of accuracy [6], the human oversight measures [7] and how you can collect, store and interpret the logs [8].
Why you need that information
You must use the system in accordance with the instructions for use [9], and you use the provider's information for your DPIA [10]. Those duties start on 2 December 2027 [11], but a DPIA may already be needed now. So include in the contract that the supplier provides and updates this information.
