Adobe announced new e-sign capapilities in document cloud.
Beside simple electronic signatures also advanced digital signatures with certificates will be integrated in Adobes eSign service. They will also comply to the comprehensive requirements of the EU as well as regulated industries. The Adobe eSign signature shall be compliant to the new german legislation (SigG, SigV) as advanced and qualified signature.
Not all of the signature features in Acrobat and Reader are legal. I doubt that a signature painted with a finger on a mobile phone will be accepted by a court:
Therefore before using an electronic signature one should always check if the receiver can accept such a signature!
The update of the eSign services in Documet Cloud will take place step by step between November 2015 and beginning of 2016.
