BRUNIERE, Luciana Scardazzi; TANAKA, Elisa Emi  e  ITO, Fábio Augusto. Integrity and authenticity's protections of digital dental radiographs. Odontol. Clín.-Cient. (Online) [online]. 2011, vol.10, n.3, pp. 211-216. ISSN 1677-3888.

Digital radiography can be used in dentistry as a substitute of the conventional system which uses radiographic film for the attainment of diagnostic images. If compared with the conventional system, digital radiography presents advantages such as shorter amount of time for the acquirement of images, possibility of an enhancement of the image quality after the exposure to the x-rays and less exposure of the patients to the x-rays. The digital system, however, has disadvantages and the most significant one is the possibility of malicious alteration of the images through graphic programs, that being, the legal value which used to be unquestionable, became judiciously debatable due to this possibility of manipulation. This article presents an overview of dental radiographs and some of the techniques that still cause interest within the research community developed to assure the authenticity, trustworthiness and integrity of the attainment, transmission and storage of digital images. The objective is that the dentists obtain knowledge about this new option of attainment of diagnosed images and becomes aware of some of the digital data protection's alternatives such as cryptography techniques and digital signatures, Digital Imaging and Communication in Medicine and the principles of digital watermarking.
