主权项

1. A system, comprising:
a processor configured to:
display an icon;indicate to a user that a received content item can be displayed in response to the user placing a finger on the displayed icon;detect a presence of a first finger of the user on the displayed icon;in response to the detection that the first finger of the first user is on the displayed icon:
permit the received content item to be displayed; anddetect a set of coordinates of the first finger of the user;detect a change in the set of coordinates of the first finger of the user;in response to detecting the change, determine that the first finger of the user, while holding the displayed icon, has moved by an amount that exceeds a threshold number of pixels, wherein the determination is indicative of an attempt by the user to take an unauthorized screen capture of the received content item while also holding down the displayed icon; andin response to determining that the movement of the first finger of the user, while holding the displayed icon, has exceeded the threshold number of pixels, prevent the user from taking the unauthorized screen capture of the received content item at least in part by ceasing display of the received content item; and a memory coupled to the processor and configured to provide the processor with instructions.
