Fig. 4 illustrates the schematic diagram according to the safety chip 103 of one embodiment of the invention.Safety chip
103 include a temporal information acquisition unit 1031, the authentication unit 1033 of memory cell 1032 and.
Temporal information acquisition unit 1031 obtains information to self-moving device 300.For example,
Temporal information acquisition unit 1031 can be a process chip, have the storage media of multiple program codes,
And/or a circuit, the function of information is obtained with self-moving device 300.
Memory cell 1032 is used to data storage.For example, memory cell 1032 can be deposited for read-only
Reservoir (read only memory, ROM).
Authentication unit 1033 is to processing data and produces data.For example, authentication unit 1033

The 300 temporal information T1 for obtaining produce identifying code A1.Data D1 includes a key, personal information
Or other confidential datas.The operation of safety chip 103 is with the flow chart explanation of Fig. 5.
Fig. 5 is refer to, Fig. 5 is illustrated according to the checking based on temporal information of one embodiment of the invention
The flow chart of method.Step S101, refer to Fig. 4 and Fig. 5, temporal information acquisition unit 1031
Temporal information T1 is obtained from an external device (ED) (such as mobile device 300).In one embodiment, when
Between information acquisition unit 1031 be connected to the memory of mobile device 300.For further, please
The flow chart of S101 the step of according to one embodiment of the invention is illustrated with reference to Fig. 6 and Fig. 7, Fig. 6.
Step S101 includes step S1011 to S1015.Fig. 7 is illustrated according to one embodiment of the invention
The schematic diagram of temporal information acquisition unit 1031 and mobile device 300.
Step S1011, the receiving record of temporal information acquisition unit 1031 (is for example moved in external device (ED)
Device 300) a current time CT and a current time zone CZ.For example, current time CT
And time zone CZ is recorded in the memory of mobile device 300 at present, and temporal information acquisition unit
The memory of 1031 self-moving devices 300 receives current time CT and current time zone CZ.
Step S1013, temporal information acquisition unit 1031 corrects mesh by obtaining a positional information L1
Preceding time zone CZ.First, temporal information acquisition unit 1031 obtains positional information L1.Positional information
L1 can be the time zone that a base station is located place, hereinafter referred to as " base station time zone ".Mobile device 300 is certainly
Base station receives a base station time zone signal.For example, if base station is seated in place " TaiWan, China ",
Then mobile device 300 receives " TaiWan, China " mobile country code, i.e. positional information L1 from base station
It is time zone "+8 ".
For further, the order of the transmission of temporal information acquisition unit 1,031 one to mobile device 300
With the place for asking base station to be located, then temporal information acquisition unit 1031 using location information from looking into
Base station time zone is obtained in table.Base station time zone corresponds to the place that base station is located.For example, if place
It is " TaiWan, China " that time zone "+8 " can be then hunted out from tabling look-up.In one embodiment, the time
Information acquisition unit 1031 does not communicate commands to mobile device 300 with the place for asking base station to be located,
But local time zone is received by the user interface of mobile device 300.In this embodiment, when local
Area is that user is input into by user interface.
Then, temporal information acquisition unit 1031 according to positional information L1 correct current time zone CZ with
Obtain correct time zone.In one embodiment, temporal information acquisition unit 1031 is according to positional information L1
Judge whether the current time zone CZ acquired by step S1011 should correct, and if current time zone CZ
Correction is needed, then temporal information acquisition unit 1031 corrects current time zone CZ according to positional information L1.
For example, temporal information acquisition unit 1031 compares current time zone CZ and base station time zone.If
Current time zone CZ is consistent with base station time zone, then temporal information acquisition unit 1031 need not be corrected at present
Time zone CZ.If current time zone CZ is inconsistent with base station time zone, temporal information acquisition unit 1031
Correct current time zone CZ.If the time zone "+8 " that current time zone CZ is "+7 " to be obtained with base station is no
Unanimously, then temporal information acquisition unit 1031 corrects current time zone CZ "+7 " to correct time zone "+8 ".
Step S1015, temporal information acquisition unit 1031 is produced according to current time CT and correct time zone
Raw universal time (Universal Time Coordinated, UTC) is used as temporal information T1.Lift
For example, when current time CT is " 13:00 " and correctly time zone is "+8 ", then temporal information takes
Unit 1031 is obtained according to current time CT " 13:00 " and correctly time zone "+8 " produces UTC time
“05:00”。
By the current time zone CZ that mobile device 300 is received is probably mistake, step is thus resulted in
UTC time produced by rapid S1015 also can be wrong.In order to produce accurate UTC time, when
Between information acquisition unit 1031 correct current time zone CZ to obtain correct time zone according to positional information L1.
Consequently, it is possible to accurate UTC time can be produced according to correct time zone.
In one embodiment, in step S101, temporal information acquisition unit 1031 may be connected to movement
The user interface of device 300 is obtaining temporal information T1.User interface can for Touch Screen, keyboard,
Microphone, or combinations of the above.For example, user can be by Touch Screen input time information
T1, and temporal information acquisition unit 1031 is from Touch Screen receiving time information T1.
In one embodiment, in step S101, temporal information acquisition unit 1031 may be connected to movement
The wireless module of device 300 is obtaining temporal information T1.Wireless module can be near-field communication (Near
Field Communication, NFC) module, Wi-Fi module, bluetooth (Bluetooth) module,
Or quick response codes (Quick Response code, QR code) module.For example, Yong Huke
Read NFC using the NFC module of mobile device 300 and identify and obtain temporal information T1, or from its
He is mobile device receiving time information T1, and then, temporal information acquisition unit 1031 is from NFC module
Receiving time information T1.
Step S103, authentication unit 1033 receives data D1, data D1 from memory cell 1032
Including a key, personal information or other confidential information.For example, authentication unit 1033 is connected
To memory cell 1032, and data D1, including key, personal information are received from memory cell 1032
Or other confidential information.
Step S105, authentication unit 1033 produces identifying code according to data D1 and temporal information T1
A1.For example, authentication unit 1033 is connected to temporal information acquisition unit 1031, and from the time
The receiving time information T1 of information acquisition unit 1031.Then, authentication unit 1033 is according to data D1
And temporal information T1 produces identifying code A1.After identifying code A1 is produced, identifying code A1 is passed
Server 500 is delivered to perform proving program.
