The problem described in the problem to be solved by the invention is not a known problem, but is independently discovered by the present inventor, and is a fact that affirms the inventive step of the invention together with the means of the present invention.

As shown in FIG. 1, the vehicle information processing system 100 includes a vehicle information processing device 1, a behavior detection unit 4, a vehicle travel information detection unit 5, an input unit 6, and an output unit 7. There is. The vehicle information processing device 1 is mainly composed of a semiconductor device, and is connected to a volatile storage unit such as a CPU (Central Processing Unit) and a RAM (Random Access Memory), a non-volatile storage unit such as a flash memory, and a communication network. It can be configured as a device having a network interface unit or the like. The information processing system 100 for a vehicle may be arranged in the vehicle and configured as one of the ECUs (Electronic Control Units).

The behavior detection unit 4 detects the behavior and outputs the behavior information. Here, the behavior detection unit 4 is, for example, the behavior of the vehicle such as an acceleration sensor for measuring the acceleration of the vehicle, a brake pressure sensor for measuring the operating pressure of the brake pedal, an in-vehicle camera for photographing the outside of the vehicle, and a position information detection (calculation) unit. Includes sensors that directly or indirectly detect. In addition, it may be used as an in-vehicle camera for photographing the inside of the vehicle or a sensor for detecting the behavior of a person in the vehicle such as the body temperature of the driver.

The vehicle travel information detection unit 5 detects a situation related to vehicle travel and converts it into vehicle travel information. The vehicle travel information detection unit 5 can detect a situation related to vehicle travel such as a microphone 52 and vehicle speed information, in addition to an in-vehicle camera 51 that captures the outside of the vehicle. The behavior detection unit 4 and the vehicle travel information detection unit 5 may overlap with each other or may be different from each other. The input unit 6 can be a keyboard, a touch panel, or the like that can be input by a driver or the like. The output unit 7 can be a display device such as a liquid crystal display device arranged at a position visible to the driver or the like.

The information processing device 1 for a vehicle has, for example, a control unit 2 composed of a CPU and a volatile storage unit, a storage unit 31 composed of a volatile storage unit and a non-volatile storage unit, and an authentication information storage unit 33. There is. The control unit 2 has a storage control unit 21 and an authentication unit 22. The storage control unit 21 "continuously acquires" "vehicle running information" related to the running of the vehicle during the "running" of the vehicle, encrypts and stores the information. The authentication unit 22 authenticates the driver who drives the vehicle related to the stored vehicle driving information, and determines whether or not the decryption is possible when the stored vehicle driving information is requested to be decoded by a driver other than the driver. Can be.

The storage unit 31 stores vehicle travel information, which is information related to vehicle travel. The condition satisfying information storage unit 32 stores the "condition satisfying time" in which the "behavior information" detected while the vehicle is traveling satisfies the "predetermined condition". Further, the storage control unit 21 continuously acquires vehicle travel information, encrypts it, and stores it in the storage unit 31. The determination unit 23 determines whether or not the behavior information of the vehicle satisfies the predetermined condition. Further, among the vehicle traveling information encrypted and stored in the storage unit 31, the storage control unit 21 determines that the condition is a predetermined period before the condition is satisfied, which is the time when the determination unit 23 determines that the predetermined condition is satisfied. The vehicle travel information corresponding to the predetermined period before the satisfaction is "decrypted" and stored in the storage unit 31.

Here, the "running" of the present invention includes not only a running state but also a temporary stop state such as a signal stop or a stop. "Vehicle running information" includes, for example, a moving image of the front of the vehicle taken by the camera 51 and other moving images of the inside and outside of the vehicle, operation information such as the speed and acceleration of the vehicle, the amount of operation of brakes and handles, position information, and the inside and outside of the vehicle.

Similar to "vehicle driving information", "behavior information" includes moving images taken inside and outside the vehicle, operation information such as vehicle speed and acceleration, amount of operation of brakes and handles, position information, voice inside and outside the vehicle, and driving. It can be information such as a sensor that detects the movement of the hand. Further, the "behavior information" may be the same information as the "vehicle running information" or different information. The "predetermined condition" means a predetermined range of behavior information, for example, if there is a change in the image that satisfies the condition by image processing in the case of a moving image, the value is equal to or less than the predetermined value in the case of numerical information. There are cases. In addition to the conditions that can be judged as an accident, the "predetermined conditions" include conditions that can be judged that an abnormality has occurred or that the vehicle has deviated from the steady state. You may. "When the condition is satisfied" means when the "predetermined condition" is satisfied, and "information when the condition is satisfied" described later is information for specifying "vehicle traveling information" when the "condition is satisfied". The “decryption” includes not only the case of decrypting the encrypted vehicle travel information but also the case of making the encrypted vehicle travel information in a decryptable state.
With such a configuration, the vehicle travel information to be protected is encrypted and the vehicle travel information to be used is decrypted, so that the vehicle travel information can be protected and used more efficiently. ..

Information processing by the vehicle information processing system 100 will be described with reference to FIG. 2 and the like. In the vehicle information processing system 100, the authentication process S10 is first performed. As shown in FIG. 3, the authentication process S10 determines whether or not the authentication unit 22 has input the ID (identifier) and password of the driver or the like via the input unit 6 or the like in step S11. If there is no input (step S11: No), the process returns to step S11 and the process is repeated. When there is an input (step S11: Yes), the corresponding authentication information is acquired from the authentication information storage unit 33 in step S12, and the ID and password are stored in the authentication information storage unit 33 in step S13. To determine if it matches. As shown in FIG. 4, for example, the authentication information storage unit 33 may include information on an ID, a password, and an encryption key used for encrypting and decrypting vehicle traveling information.

In the case of a negative determination in step S13 (step S13: No), the process returns to step S11 and the process is repeated. In the case of a positive determination in step S13 (step S13: Yes), in step S14, the fact that the authentication is successful is displayed in the output unit 7, and in step S15, the ID and encryption key information is transmitted to the storage control unit 21. And end the process.

Returning to FIG. 2, the storage control unit 21 that has received the ID and encryption key information executes the vehicle traveling information storage process S60. As shown in more detail in FIG. 5, the vehicle travel information storage process S60 activates the behavior detection unit 4 in step S61 when the vehicle first starts traveling. In the present embodiment, an example of using an acceleration sensor for detecting the acceleration of the vehicle and a brake pressure sensor for detecting the pressure of the depressed brake pedal as the behavior detection unit 4 will be described, but other behavior detection units 4 will be described. It may be used.

Subsequently, in step S31, the determination unit 23 determines whether or not the acceleration is, for example, 10 m / s ² or more. When it is 10 m / s ² or more (step S31: Yes), it is determined in step S32 whether the brake pressure is, for example, 10 kgf / s ² or more. If a negative determination is made in step S31 or S32, the process proceeds to the encrypted storage process S20, and the vehicle travel information is encrypted and stored.

In the sequence diagram of FIG. 2, the encrypted storage process S20 is executed after the authentication process S10 is completed. In this sequence diagram, the captured image taken by the camera 51 will be described as an example of the vehicle travel information, but other vehicle travel information may be used. In the encrypted storage process S20, in step S21, the storage control unit 21 acquires a captured image taken by the camera 51, which is the vehicle travel information detection unit 5. After that, the captured image acquired in step S22 is encrypted, and the captured image encrypted in step S23 is stored in the storage unit 31. FIG. 6 shows the file information of the vehicle traveling information stored in the storage unit 31 by the encrypted storage process S20, the encryption flag is 1 at each time, and the image is encrypted (Enc: Encrypted). It is shown that. The traveling data may be data stored in association with the shooting information which is the vehicle traveling information and the behavior information at the same time.

Returning to FIG. 5, when the brake pressure is 10 kgf / s ² or higher in step S32 (step S32: Yes), the determination unit 23 determines that the vehicle behavior information satisfies the predetermined condition, and the storage control unit 21 The process shifts to the unencrypted storage process S40 in. Here, the predetermined condition may be determined by machine learning based on the accumulation of information detected by the behavior detection unit 4. In this case, the normal behavior can be excluded and the behavior at the time of abnormality can be detected. The behavior at the time of an abnormality can be, for example, a behavior for detecting the occurrence of a traffic accident.

The storage control unit 21 performs the unencrypted storage process S40 for storing the vehicle traveling information without encryption for a predetermined period (for example, 10 seconds) after the condition is satisfied. FIG. 2 shows the unencrypted storage process S40. In the unencrypted storage process S40, in step S41, the storage control unit 21 acquires a captured image captured by the camera 51. After that, the captured image that is not encrypted in step S42 is stored in the storage unit 31.

Returning to FIG. 5, on the other hand, the storage control unit 21 performs a decryption / storage process S50 for decrypting the vehicle traveling information for a predetermined period (for example, 10 seconds) before the condition is satisfied, which is encrypted and stored in the storage unit 31. FIG. 2 shows the decoding / saving process S50. In the decoding / saving process S50, in step S51, the storage control unit 21 acquires an encrypted image taken at a predetermined time before the condition is satisfied from the storage unit 31. After that, the captured image acquired in step S52 is decoded, and the captured image decoded in step S53 is stored in the storage unit 31 as a captured image for a predetermined time before the condition is satisfied.

Returning to FIG. 5, the storage control unit 21 shifts to the encrypted storage process S20 after the decryption / storage process S50. Specifically, the storage control unit 21 encrypts and stores the captured image (vehicle running information) after a predetermined period (for example, 10 seconds) after the condition is satisfied. FIG. 7 shows the file information of the vehicle traveling information stored in the storage unit 31 processed as described above. Further, FIG. 8 shows the encrypted state of the vehicle traveling information stored in the storage unit 31. As shown in these figures, assuming that the time when the condition is satisfied is, for example, time T30, the encryption is performed in the predetermined period before the condition is satisfied (for example, 10 seconds: T20 to T30) and the predetermined period after the condition is satisfied (for example, 10 seconds: T30 to T40). The encryption flag is 0, and the shooting information is stored without being encrypted. As the predetermined time before the condition is satisfied and the predetermined period after the condition is satisfied, a certain period may be determined in advance, or a period specified by a certain rule may be obtained.

In the present embodiment, the storage control unit 21 decodes and stores the vehicle traveling information for a predetermined period before the condition is satisfied when the condition is satisfied. In this way, when decoding is performed when the conditions are satisfied, a third party can perform the necessary vehicle driving information from the time when the conditions are satisfied to a predetermined time before, without performing the decoding process when the vehicle driving information is taken out. Can be obtained. Further, since the storage control unit 21 stores the vehicle traveling information for a predetermined period after the condition is satisfied without being encrypted, which is a predetermined period after the condition is satisfied, a third party can perform the condition without performing decryption processing later. It is possible to acquire necessary vehicle driving information from the time of satisfaction to a certain period of time. Instead of decoding the vehicle traveling information, it may be in a state where it can be decoded. For example, only the encryption flag shown in FIG. 7 is turned ON, the driving data is kept encrypted, and when the driving data is fetched, even if the driver is not an authenticated driver, the driver is associated with the ID of the driver. Only the part where the encryption flag is 0 may be decrypted by using the obtained key.

FIG. 9 is a sequence diagram showing a modified example of processing by the vehicle information processing system 100. In this modification, if the predetermined conditions are satisfied in steps S31 and S32, the condition satisfying information is stored in the condition satisfying information storage unit 32 in step S33. The condition satisfying information is information for specifying the "vehicle traveling information" corresponding to the "condition satisfying time" in the vehicle traveling information storage unit 31. For example, it may be time information when the condition is satisfied, or it may be the address or index information of the storage unit 31 in which the vehicle traveling information is stored. The information storage unit 32 when the conditions are satisfied may be provided in the vehicle travel information storage unit 31. Further, in this modification, the unencrypted storage process S40 and the decryption storage process S50 are not executed when the conditions are satisfied. Therefore, as shown in FIG. 10, all the vehicle traveling information stored in the storage unit 31 is encrypted. Instead, when the predetermined access is detected in step S71, the storage control unit 21 acquires the condition satisfying information from the condition satisfying information storage unit 32 in step S72, and executes the decoding / saving process S80. In the decoding / saving process S80, in step S81, the storage control unit 21 takes images encrypted from the storage unit 31 based on the acquired information at the time of condition satisfaction, at a predetermined time before the condition is satisfied and at a predetermined time after the condition is satisfied. Get an image. After that, the captured image acquired in step S82 is decoded, and the captured image decoded in step S83 is stored in the storage unit 31 as a captured image for a predetermined time before the condition is satisfied and a predetermined time after the condition is satisfied. As a result, the captured image stored in the storage unit 31 is in an encrypted state similar to the encrypted state shown in FIG. When the decoded captured image is immediately transmitted to the outside, it is not always necessary to save it in the storage unit 31.

Here, the detection of the predetermined access can be, for example, the detection of a signal indicating that the "portion including the storage unit 31" is removed. In this case, for example, when used in verification of a traffic accident, etc., the necessary part of the vehicle driving information can be used because it is not encrypted, and the other parts are encrypted, so that the vehicle travels. Information can be kept safe. Further, the detection of the predetermined access can be the detection that the predetermined information has been input. For example, since decryption is performed by inputting predetermined information such as a password owned by a person who has a confidentiality obligation, only the person who has a confidentiality obligation can use the necessary information. Here, the predetermined information may be input via a public network, and in this case, by inputting via a public network such as the Internet, confidentiality is obliged more quickly and surely. The necessary information can be obtained by a person with a network. The "part including the storage unit" of the present invention includes the information processing apparatus itself.

Therefore, in the modified example of FIG. 9, since the vehicle running information for a predetermined period before and after the condition is satisfied is decoded when a predetermined access is detected, the vehicle running information is kept safe until the predetermined access is obtained. Can be done. In the present embodiment, the predetermined period before and after the condition is satisfied is set, but either before or after the condition is satisfied may be decoded.

Further, in the above-described embodiment, the storage control unit 21 may decode in order from "vehicle traveling information with higher confidentiality". Here, the "vehicle traveling information with higher confidentiality" of the present invention is information having a relatively high degree of personal information, for example, position data or data taken by a camera 51. As a result, by first decoding the vehicle traveling information with higher confidentiality, important information can be used even if the decoding process becomes difficult in the middle.

On the other hand, the storage control unit 21 may decode in order from "vehicle traveling information with lower confidentiality". Here, the "vehicle traveling information with lower confidentiality" of the present invention is information having a relatively low degree of personal information, such as data such as speed, acceleration, and steering wheel operation amount. This makes it possible to keep the highly confidential vehicle driving information in a safe state for a longer period of time.
