Abstract
An automated device and method for erasing data stored in non-volatile memories (M) of electronic devices (A), such as smartphones or tablets. The device uses an irradiation chamber (1) comprising at least one X-ray source (S) confined in a X-ray-tight enclosure, capable of receiving a plurality of electronic devices (A) that can be brought into the chamber (1) by a conveyor (2). A control unit (CU) controls the conveyor (2) and the X-ray source (S) to irradiate each electronic device (A) with controlled power and duration for erasing data stored in the non-volatile memories (M) of said electronic devices (A).
Claims18
An automated device for erasing data stored in non-volatile memories of electronic devices,
- wherein said automated device comprises:
- an irradiation chamber comprising at least one X-ray source confined in an X-ray- tight enclosure and capable of successively receiving said electronic devices to be brought into the chamber by a conveyor,
- an identification device for recognizing a type of said electronic devices and/or a type of memory of each of said electronic devices to irradiate;
- and
- a control unit controlling the conveyor and said X-ray source to irradiate said each of said electronic devices with controlled power and duration as a function of irradiation parameters corresponding to the device identified by said identification device, for erasing data contained in the non-volatile memories of said electronic devices without inducing physical damage or permanent modification of cells in said memories,
- wherein said X-ray source generates an X-ray beam irradiating said devices along a principal axis that is inclined or inclinable with respect to a plane of said conveyor, and wherein an angle of the principal axis is determined by said control unit according to said identification.
A method for erasing data stored in non-volatile memories of electronic devices, wherein the method comprises:
- an identification of each of said electronic devices for recognizing a type of said electronic devices and/or a type of memory of each of said electronic devices to irradiate,
- a determination, by a control unit, of irradiation parameters corresponding to said electronic devices identified in said identification, and
- an irradiation of said electronic devices with at least one X-ray source confined in a X-ray-tight enclosure of an irradiation chamber capable of successively receiving said electronic devices to be brought into the chamber by a conveyor, the conveyor and said X-ray source being controlled by said control unit according to said irradiation parameters including power and duration of irradiation for erasing data contained in the non-volatile memory of said electronic devices without inducing physical damage or permanent modification of cells in said memories,
- wherein a principal axis of an X-ray beam is generated by said X-ray source, the principal axis being inclined or inclinable with respect to a plane of said conveyor, and the angle of the principal axis being determined per said control unit according to said identification.
