Mae gennym ni drefniadau cadarn ac uchel eu parch ar gyfer ymchwilwyr cymeradwy i gael mynediad diogel i ddata iechyd trwy'rSAIL Databank(Cysylltu Gwybodaeth Ddienw yn Ddiogel). Mae SAIL yn flaenllaw ar gyfer storio a defnyddio data dienw sy’n seiliedig ar berson at ddibenion ymchwil foesegol ac mae wedi bod yn rhan bwysig o'n hymateb i’r pandemig Covid-19. Dim ond ar gyfer ymchwilwyr cymeradwy y rhoddir mynediad i'r data dienw hwn, yn amodol ar brosesau cymeradwyo moesegol llym. Yn gyffredinol, dim ond trwy Borth diogel SAIL y gellir gweld a dadansoddi'r data. Mewn amgylchiadau eithriadol lle mae angen trosglwyddo'r data, mae angen cymeradwyaeth benodol perchennog y data.
We already have robust and well-regarded arrangements in place for approved researchers to gain secure access to health data through theSAIL Databank(Secure Anonymised Information Linkage). This is a world-class flagship for the secure storage and use of anonymised person-based data for ethical research purposes and has been an important part of our Covid-19 pandemic response.  Access to this anonymised data is only granted for approved researchers, subject to strict ethical approval processes. The data can generally only be viewed and analysed through the secure SAIL Gateway. In the exceptional circumstances where the data does need to be transferred, it requires the explicit approval of the data owner.
