A temporary exchange of contact data may be provided between a first UE and a second UE via a wireless communication network according to one or more policies, user preferences, historical data, a defined physical or virtual proximity between the first UE and the second UE, or a combination thereof. The contact data may be automatically deleted between the first UE and the second UE according to the one or more policies, the user preferences, the historical data, the defined physical or virtual proximity between the first UE and the second UE, or a combination thereof. ## Claims ### Claim 1 A method for intelligent temporary contact sharing between user equipment (UE) by a processor, comprising: creating a temporary ad-hoc network of a plurality of users in a cloud computing environment, the temporary ad-hoc network having a defined network location circumscribing the plurality of users; providing a temporary exchange of contact data between a first user equipment (UE) associated with a first one of the plurality of users and a second UE associated with a second one of the plurality of users via a wireless communication network according to one or more policies, user preferences, historical data, and a defined physical or virtual proximity between the first UE and the second UE within the defined network location; wherein the first UE and the second UE are each mobile devices; responsive to exchanging the contact data and while the first UE and the second UE are within the defined network location, initializing a machine learning operation to monitor communication interactions between the first UE and the second UE; wherein the machine learning operation deduces an association level and a maturity of the association level over time of those of the plurality of users operating the first UE and the second UE according to the monitored communication interactions; upon determining that either of the first UE and the second UE has exited the defined network location by moving farther than a predetermined physical distance from one another outside the defined network location of the ad-hoc network, starting a timer on the first UE or the second UE that exited; and upon an expiration of a predetermined time period on the timer, automatically permanently retaining or automatically deleting the contact data between the first UE and the second UE according to the one or more policies, user preferences, historical data, and the deduced association level and the maturity of the association level determined by the machine learning operation between those of the plurality of users operating the first UE and the second UE while in the defined network location; wherein upon moving farther than the predetermined physical distance from one another, a notification is provided to each of the first UE and the second UE indicating which one of the first UE or the second UE has moved to a location outside the defined network location. ### Claim 2 (depends on 1) The method of claim 1, further including triggering the temporary exchange of the contact data between the first UE and the second UE by tapping the first UE with the second UE using near field communication (NFC). ### Claim 3 (depends on 1) The method of claim 1, further including dynamically revoking, reinstating, or reauthorizing the temporary exchange of the contact data between the first UE and the second UE according to the one or more policies, the user preferences, the historical data, the defined physical or virtual proximity between the first UE and the second UE, or a combination thereof. ### Claim 4 A system for intelligent temporary contact sharing between user equipment (UE), comprising: one or more computers with executable instructions that when executed cause the system to: create a temporary ad-hoc network of a plurality of users in a cloud computing environment, the temporary ad-hoc network having a defined network location circumscribing the plurality of users; provide a temporary exchange of contact data between a first user equipment (UE) associated with a first one of the plurality of users and a second UE associated with a second one of the plurality of users via a wireless communication network according to one or more policies, user preferences, historical data, and a defined physical or virtual proximity between the first UE and the second UE within the defined network location;
