Security article authentication

A mobile device, comprising:

• a plurality of light emission devices disposed in a component cluster on an external surface of a back side of the mobile device;
• a plurality of optical sensor devices disposed in the component cluster on the external surface of the back side of the mobile device;
• one or more memories;
• and
• one or more processors, coupled to the one or more memories, configured to cause the mobile device to:
• cause a first light emission device, of the plurality of light emission devices disposed in the component cluster on the external surface of the back side of the mobile device, to emit, at a security article, light associated with a first spectral range;
• cause a second light emission device, of the plurality of light emission devices disposed in the component cluster on the external surface of the back side of the mobile device, to emit light associated with a second spectral range;
• obtain from a first set of one or more optical sensor devices of the plurality of optical sensor devices disposed in the component cluster on the external surface of the back side of the mobile device, and based on the light associated with the first spectral range being emitted, first sensor data associated with the security article;
• obtain from a second set of one or more optical sensor devices of the plurality of optical sensor devices disposed in the component cluster on the external surface of the back side of the mobile device, and based on the light associated with the second spectral range being emitted, second sensor data associated with the security article;
• determine, based on the first sensor data and the second sensor data, one or more characteristics of a security feature of the security article;
• determine, based on the one or more characteristics of the security feature, whether the security article is authentic;
• and
• cause, based on whether the security article is authentic, one or more actions to be performed.

One or more non-transitory computer-readable media storing a set of instructions, the set of instructions comprising:

• one or more instructions that, when executed by one or more processors of a mobile device, cause the mobile device to:
• cause light to be emitted at a security article by one or more of a plurality of light emission devices disposed in a component cluster on an external surface of a back side of the mobile device;
• obtain, from a plurality of optical sensor devices disposed in the component cluster on the external surface of the back side of the mobile device, and based on the light being emitted, sensor data associated with the security article;
• determine, based on the sensor data, one or more characteristics of a security feature of the security article;
• determine, based on the one or more characteristics of the security feature, whether the security article is authentic;
• and
• cause, based on whether the security article is authentic, one or more actions to be performed.
