From the prospect of the protection of data, the treatment of images of the cells, although he can justify itself in determinate cases, it has to be exceptional in accordance with the considerations of this judgement. It can be reasonable to pick up and to record images in rooms of search when superficial registers of the persons stopped, since a contact is produced between these and third parties, are practiced. In one and another case, it is necessary to take the possibility to treat the images in an encrypted way, as well as the exigible safety measures, in order to avoid undue accesses or inappropriate treatments of the images, into account. Regarding the conservation of the recorded images, it does not seem that in many cases it has to be exhausted the deadline of a month, since, probably, very before it will already be able to be determined if it is necessary to preserve or not the images.
