Method and system for a computer-based, secured communication between data processing units

A non-transitory computer-readable storage medium with computer-readable instructions stored on the storage medium, the computer-readable instructions being executable on at least one processor of a mobile device of a sender and on at least one processor of a mobile device of at least one contact, for establishing a computer-based, secured and controlled communication with at least one mobile device of at least one contact, the computer readable instructions when executed by the processor perform:

• storing an alphanumeric or image data set in a cloud network of remote servers hosted on the Internet;
• displaying an alphanumeric or image data set selected by the sender as a pixelated data set on a display of the mobile device of the sender before sending it to the mobile device of the at least one selected contact;
• selecting at least one contact from a contact list by the sender and sending the pixelated data set to the mobile device of the at least one selected contact;
• transmitting by the sender an authorization to one of the remote servers, and storing the authorization on the one remote server, the authorization indicating that the at least one selected contact may view the alphanumeric or image data set in an un-pixelated manner on a display of the mobile device of the at least one selected contact;
• communicating of the mobile device of the at least one selected contact with the one remote server in real time in order to request the authorization after receipt of a message of the sender that a pixelated data set has been sent;
• and
• removing in real time the pixelation of the pixelated data set sent by the sender if an authorization of the contact exists on the one remote server
• wherein the sent and pixelated data set is provided with a logo of an application program comprising the computer-readable instructions, the logo indicating to an authorized contact that an application program is to be loaded on the mobile device for viewing, on a screen of the mobile device of the at least one selected contact, the received pixelated data set in an un-pixelated manner.

A system for a computer-based, secured and controlled communication between a mobile device as sender and at least one further mobile device as receiver, the system comprising:

• a cloud network of remote servers hosted on the Internet for storing an alphanumeric or image data set;
• one of the remote servers communicatively coupled to the mobile device of the sender and the at least one further mobile device;
• a processor of the mobile device of the sender with an application program executable by the processor, the program generating a pixelated data set from an alphanumeric or image data set;
• an input device of the mobile device of the sender for allowing the sender to select at least one contact to which the pixelated data set can be sent, the input device being authorized to view the alphanumeric or image data set in an un-pixelated manner, wherein the authorization is stored on the one remote server by the mobile device of the sender;
• and
• a processor of the at least one further mobile device with the application program loaded thereon and executable by the processor in order to restore the alphanumeric or image data set out of the pixelated data set, wherein the further mobile device of the at least one contact requests the authorization from the one remote server before executing the application program in real time;
• wherein the pixelated data set shows a logo of the application program, and wherein the logo is a button by which the application program is loadable on the at least one mobile device for viewing, on a screen of the mobile device of the at least one selected contact, the received pixelated data set in an un-pixelated manner.
