Determining a security state based on communication with an authenticity server

A non-transitory computer-readable storage medium storing computer-readable instructions, which when executed, cause a server to:

• receive, from a mobile device, data regarding a first application to be installed on the mobile device, wherein the mobile device stores a device state that can include states of trusted, untrusted, or unknown;
• determine a source of the first application;
• send, to an authenticity server, data regarding the source;
• receive, from the authenticity server, a first state designation for the first application, wherein the first state designation received from the authenticity server can include states of trusted or untrusted;
• in response to receiving the first state designation, set a second state designation;
• and
• send the second state designation to the mobile device, wherein sending the second state designation to the mobile device causes changing of the device state from unknown to the first state designation.

A method comprising:

• receiving, from a first computing device, data regarding a first application;
• in response to receiving the data regarding the first application, determining first data regarding a source of the first application;
• sending the first data regarding the source over a network to an authenticity server;
• receiving, from the authenticity server, a first state designation for the first application, wherein the authenticity server determines the first state designation based on the first data;
• in response to receiving the first state designation, setting a second state designation that is different from the first state designation;
• and
• sending the second state designation to the first computing device.
