Instant Simultaneous Messaging

A method for exchanging instant simultaneous messages (31) between a sending user (33) and plurality, from one to many, of target users (35):

• said instant simultaneous message (31) including a sending (33) and plurality of target (35) users' particulars, i.e. user identification, a subject (36) and multiple contents (37), one for the sending user (33) and one for each of the target users (35), said subject (36) and said contents (37) including a text or a media or a combination of both, and are associated with a date, i.e. the date/time when the said sending user (33) submits the said instant simultaneous message (31), or a location, i.e. the position and/or geographic coordinate and/or GPS where the said sending user (33) submits the said instant simultaneous message (31), or a delivery status, i.e. the status which indicates if the said instant simultaneous message (31) is sent and/or delivered and/or received and/or has been seen by whom including the said sending user (33) and/or each of the said target users (35), or a combination of any or none and said text including question, comment, review, opinion or feedback and said media including photo, video or audio and said delivery status indicating to either each or a predefined subset of the users defined by the sending user, the current status of the instant simultaneous message (31) including whether the said instant simultaneous message (31) is sent and/or delivered and/or received and/or has been seen by whom including the said sending user (33) and/or each of the said target users (35);
• said sending user sends all the components of the instant simultaneous message except the said content to all the said target users;
• said target users (35) and the said sending user, each sends its own encrypted content (37) of the instant simultaneous message to all the other users, from the said sending user and said target users;
• a pair of users, from the said sending user and said target users, will exchange their encryption key of their encrypted content with each other once each received the encryption content of the other user.

A set of instructions on a non-transitory computer-readable storage medium that when executed on at least one processor results to exchanging instant simultaneous messages (31) between a sending user (33) and plurality, from one to many, of target users (35) via an intermediate (32):

• said intermediate (32) is a Unified Instant Messaging System (UIMS) or a computing unit that is a thread/process of a single/multi processor or a distributed/cloud based system;
• said instant simultaneous message (31) including a sending (33) and plurality of target (35) users' particulars, i.e. user identification, a subject (36) and multiple contents (37), one for the sending user (33) and one for each of the target users (35), said subject (36) and said contents (37) including a text or a media or a combination of both, and are associated with a date, i.e. the date/time when the said sending user (33) submits the said instant simultaneous message (31), or a location, i.e. the position and/or geographic coordinate and/or GPS where the said sending user (33) submits the said instant simultaneous message (31), or a delivery status, i.e. the status which indicates if the said instant simultaneous message (31) is sent and/or delivered and/or received and/or has been seen by whom including the said sending user (33) and/or each of the said target users (35) and/or the said intermediate (32), or a combination of any or none and said text including question, comment, review, opinion or feedback and said media including photo, video or audio and said delivery status indicating to either each or a predefined subset of the users defined by the sending user, the current status of the instant simultaneous message (31) including whether the said instant simultaneous message (31) is sent and/or delivered and/or received and/or has been seen by whom including the said sending user (33) and/or each of the said target users (35) and or the said intermediate (32);
• said sending user sends all the components of the instant simultaneous message except the contents of target users (37) to the said intermediate (32) via the said network;
• said intermediate (32) hides the content (37) of the sending user (33) and sends the resulted instant simultaneous message (31), i.e. the received instant simultaneous message from the sending user without the sending user's content to all the target users (35);
• said target users (35) each sends its own content (37), i.e. target user's content of the instant simultaneous message, according to the subject (36) to the intermediate (32);
• said intermediate (32) is continuing to receive contents of the said instant simultaneous message (31) from each of the target users (35) initially indicated by the said sending user and for each received said content of the said instant simultaneous message (31) from any of the target users updates the sending user and those target users who already sent their said content of the said instant simultaneous message (31) to the intermediate with the said received content.
