Abstract: A method manages an access and display service of confidential information and data (DAT) by a computer system including at least one user electronic device. The method includes selecting, by a processing unit of the computer system, the DAT to be displayed based on a unique identifier associated with the DAT. The DAT is acquired in encrypted form from a memory unit of the computer system. The method decrypts the DAT in encrypted form to generate a plaintext information or data. A virtual desktop associated with the electronic device is generated and includes generating the virtual desktop on the display of the electronic device and providing the generated virtual desktop only with the process associated with an executable file representative of the unique identifier of the DAT to be displayed. A message is provided containing the plaintext information or data to be sent to the virtual desktop for display.
