Description

Technical Field

[0001] The present application relates to the technical field of data storage, and in particular to a portable solid-state hard drive. Background Art

[0002] Portable Solid State Drive (PSSD) has the advantages of low noise, small size, fast reading and writing speed, etc. As a data storage device, it has become the first choice for people's office and entertainment.

[0003] Users can store daily data in PSSD. When using it, they sometimes need to hand over PSSD to others. This may lead to illegal access to personal data, resulting in personal data leakage and posing security risks. Summary of the Invention

[0004] The present application provides a portable solid-state drive (PSSD) that can improve the security of a PSSD.

[0005] In the first aspect, the present application provides a PSSD, which includes: a controller, a memory chip electrically connected to the controller, a Bluetooth module, and an interface; wherein the memory chip includes: a first storage area and a second storage area, the first storage area corresponds to disk No. 1; the second storage area corresponds to disk No. 2; disk No. 1 is an ordinary storage disk, and disk No. 2 is a secret storage disk; the Bluetooth module is used to communicate with an external Bluetooth device installed with a preset APP; the controller is used to report information of disk No. 1 and disk No. 2 to the host through the interface when the APP has not set a password for disk No. 2 and the PSSD is electrically connected to the external host through the interface; the controller is also used to report information of disk No. 1 and disk No. 2 to the host through the interface when the APP has set a password for disk No. 2 and the PSSD is electrically connected to the external host through the interface; When electrically connected to the host, the information of disk No. 1 is reported to the host through the interface, but the information of disk No. 2 is not reported; the controller is also used to report the information of disk No. 1 and disk No. 2 to the host after the password of disk No. 2 has been set by the APP, the host has mounted disk No. 1 and has not mounted disk No. 2, and the connection request carrying password information obtained through the APP is verified; the Bluetooth module is also used to obtain the password set for disk No. 2 by the external Bluetooth device through the APP when the external Bluetooth device sets the password for the second disk through the APP; and to obtain the connection request carrying password information sent by the external Bluetooth device through the APP after the PSSD is electrically connected to the host through the interface and connected to the external Bluetooth device through Bluetooth.

[0006] In a possible implementation, the controller is further configured to obtain a password set by the APP for the second disk and store the password in a storage chip.

[0007] In one possible implementation, the PSSD also includes: an antenna and a buzzer electrically connected to the Bluetooth module, and a power module electrically connected to the buzzer and the Bluetooth module; the Bluetooth module sends signals and receives information through the antenna; the Bluetooth module is also used to drive the buzzer to alarm when receiving a search message sent by the APP; the power module is used to supply power to the Bluetooth module and the buzzer when the PSSD is not connected to the host, so that the PSSD operates in anti-loss and search mode.

[0008] In a possible implementation, the power module includes a rechargeable battery; the power module is further configured to obtain power from the host for charging when the PSSD is electrically connected to the host through an interface.

[0009] In a possible implementation, the rechargeable battery is a button cell battery or a polymer battery.

[0010] In one possible line-of-sight approach, the PSSD further includes a magnet for enabling the PSSD to be attached to a surface of an external device.

[0011] In one possible implementation, the controller is further configured to obtain a connection request from the APP through the Bluetooth module, and when verification fails, dynamically adjust the response time of subsequent verification connection requests according to a preset time interval and the accumulated number of errors.

[0012] This application sets up disk 1 and disk 2, where disk 2 is used as a secret storage disk, which can provide users with an additional secure storage area for storing sensitive or private data, thereby reducing the risk of data being illegally accessed. When the PSSD is electrically connected to an external host, the controller can decide whether to report the information of disk 2 based on whether a password has been set for disk 2. This provides more fine-grained access control, ensuring that only authorized users can access the data in the secret storage area. This application can use a Bluetooth module to communicate with an external Bluetooth device. Users can set and manage passwords for disk 2 through devices with preset APPs installed. This wireless password management method improves the convenience of user operations. When the external host mounts disk 1 but not disk 2, the controller will report the information of disks 1 and 2 only after the connection request carrying password information obtained through the APP is verified, which increases security and prevents unauthorized access through security verification. In addition, users can connect wirelessly to external Bluetooth devices through the Bluetooth module, simplifying the password setting and verification process, and completing sensitive operations without physical contact with the PSSD. The technical solution provided by this application also enables the following: when the PSSD is given to others for use, because the second drive is password-protected, even if the data on the first drive can be accessed, the sensitive data on the second drive is also protected. Before the password is verified, the second drive will not be mounted and is invisible to other users, effectively being in a "non-existent" state. This effectively prevents unauthorized users from accessing personal data stored on the second drive, improving data security. It also helps reduce the risk of data loss due to device loss or theft.

[0018] The present application will be further described in detail below with reference to the accompanying drawings and examples. It should be understood that the specific embodiments described herein are intended only to illustrate the relevant invention and are not intended to limit the invention. It should also be noted that, for ease of description, only a portion relevant to the invention is shown in the accompanying drawings.

[0019] It should be noted that, in the absence of conflict, the embodiments and features of the embodiments in this application can be combined with each other. The present application will be described in detail below with reference to the accompanying drawings and in combination with the embodiments.

[0020] In the embodiments of this application, the terms "first," "second," and the like are used for descriptive purposes only and should not be understood to indicate or imply relative importance or to implicitly indicate the number of the technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of the features. In the description of this embodiment, unless otherwise specified, "plurality" means two or more.

[0021] Figure 1A Schematic diagram of an application scenario of PSSD provided by an embodiment of the present application; Figure 1A As shown, the mobile phone 101 can communicate with the PSSD 102 via Bluetooth, and the PSSD 102 can communicate with the host 103 via a data cable. It should be noted that in actual use, it is not necessary to use the three devices together. Figure 1B As shown, the mobile phone 101 is connected to the PSSD 102 via Bluetooth. The mobile phone 101 can install a preset APP and use the preset APP to set a password for the storage disk corresponding to the secret storage area in the storage chip. As shown in 1C, in some scenarios, the PSSD 102 may be lent to others for use, and others may connect the PSSD 102 to the host via a data cable. Figure 1C The computer 103 shown in FIG.

[0022] In some embodiments, PSSD102 includes a memory chip, which includes: a first memory area and a second memory area, the first memory area corresponds to disk No. 1; the second memory area corresponds to disk No. 2; disk No. 1 is a common memory disk, and disk No. 2 is a secret memory disk; when disk No. 2 is not set with a password by a preset APP, and PSSD102 is electrically connected to host 103 through an interface, host 103 obtains information of disk No. 1 and disk No. 2 reported by PSSD102, and mounts disk No. 1 and disk No. 2; disk No. 1 is a common memory disk, and disk No. 2 is a secret memory disk; the password of disk No. 2 is set by a preset APP; Figure 1BAs shown, a password is set for disk number two via a Bluetooth device such as a mobile phone 101 with a preset app installed. When a password is set for disk number two and PSSD 102 is electrically connected to the host via an interface circuit, the host mounts disk number one and does not mount disk number two. When a password is set for disk number two and the host mounts disk number one and does not mount disk number two, the host mounts disk number one and disk number two after the password input by the PSSD via the app is verified by the PSSD.

[0023] like Figure 2 As shown, an embodiment of the present application provides a secure, efficient and user-friendly data storage solution. Figure 2 The PSSD 200 shown includes a controller 201 , a Bluetooth module 202 electrically connected to the controller 201 , a storage chip 203 , and an interface 204 .

[0024] The storage chip 203 includes: a first storage area and a second storage area, the first storage area corresponds to disk No. 1; the second storage area corresponds to disk No. 2; disk No. 1 is a common storage disk, and disk No. 2 is a secret storage disk. The Bluetooth module 202 is used to communicate with an external Bluetooth device such as a mobile phone or other electronic device that has a preset APP installed. The controller 201 is used to report the information of disk No. 1 and disk No. 2 to the host through the interface when the APP has not set a password for disk No. 2 and the PSSD200 is electrically connected to an external host such as a computer or other electronic device through the interface 204. The controller 201 is also used to report the information of disk No. 1 to the host through the interface 204, but not report the information of disk No. 2, when the APP has set a password for disk No. 2 and the PSSD200 is electrically connected to the host through the interface 204. The controller 201 is also used to report the information of disk No. 1 and disk No. 2 to the host after the password of disk No. 2 has been set by the APP, disk No. 1 is mounted on the host, disk No. 2 is not mounted, and the connection request carrying password information obtained through the APP is verified; the Bluetooth module 202 is also used to obtain the password set for disk No. 2 by the external Bluetooth device through the APP when the external Bluetooth device sets the password for the second disk through the APP; and to obtain the connection request carrying password information sent by the external Bluetooth device through the APP after the PSSD200 is electrically connected to the host through the interface 204 and connected to the external Bluetooth device via Bluetooth.

[0025] It should be noted that the interface 204 may be a USB Type-C interface, which may support connection with an external host device. The interface 204 may not only be used for data transmission, but also provide power for the PSSD 200 .

[0026] The Bluetooth module 202 enables the PSSD 200 to communicate wirelessly with external Bluetooth devices such as mobile phones, tablets, etc. In some possible implementations, the Bluetooth module 202 may use Bluetooth Low Energy (BLE) technology to ensure stable connection and low-energy communication with external devices.

[0027] The memory chip 203 is the data storage medium of the PSSD 200. In some possible implementations, flash memory technology can be used to provide high-speed read and write performance and high reliability. The memory chip can be divided into two independent storage areas: disk 1 and disk 2. Disk 1 serves as the general storage area for storing daily data; disk 2 serves as the secret storage area for storing sensitive or private data. It should be noted that in some possible real-time implementations, the storage space of disks 1 and 2 can be the same. In some possible real-time implementations, the storage space of disks 1 and 2 can be different, such as disk 1 having more storage space than disk 2, or disk 2 having more storage space than disk 1. In some possible real-time implementations, the storage space of disks 1 and 2 can be fixed. In some possible real-time implementations, the storage space of disks 1 and 2 can be configurable and can be configured as needed, such as using a mobile phone through a pre-set app to configure the storage space of disks 1 and 2. Furthermore, as the amount of stored data changes, in some possible implementations, the storage space of the first disk and the second disk may be dynamically adjusted.

[0028] It should be noted that the controller 201 of PSSD200 can decide whether to report the information of the second disk according to whether the second disk has a password set. When PSSD200 is electrically connected to the external host through the interface 204, if the second disk has not been set with a password by the preset APP, the controller 201 will report the information of the second disk to the host (for example, Figure 1A The computer 103) reports the information of the first disk and the second disk.

[0029] To enhance data security, controller 201 is designed with a password protection mechanism. When a password is set for disk 2, controller 201 will only report information from disk 1 to the host, not disk 2. This effectively prevents unauthorized access and helps protect user privacy.

[0030] It should be noted that in this embodiment of the application, the PSSD200 also features a unique security verification mechanism. When the external host mounts drive 1 but not drive 2, and the connection request with password information obtained through the app passes verification, the controller will report the information of drive 1 and drive 2 to the host. This mechanism not only improves data security but also provides users with a convenient way to access data.

[0031] Bluetooth module 202 plays a crucial role in PSSD 200. It not only communicates with external devices but also retrieves the password set for the second drive via the app. This allows users to remotely set and manage the password for the second drive, improving operational convenience.

[0032] When PSSD 200 is electrically connected to the host through interface 204 and connected to an external Bluetooth device via Bluetooth, the Bluetooth module is also used to receive connection requests containing password information sent by the external Bluetooth device through the app. This mechanism ensures that only authenticated devices can access data in the PSSD, enhancing data security.

[0033] The PSSD provided in the embodiment of the present application can be applied in a variety of scenarios, such as: business office, personal entertainment, education, travel, etc. Among them, in business office, business people often need to store and transmit sensitive data, such as business plans, financial statements, etc. The second disk of the PSSD provides a secure storage area to ensure the security of these data. During personal entertainment, users can use the first disk of the PSSD to store entertainment content such as music, videos, photos, and store personal privacy files in the second disk, such as personal diaries, private photos, etc. In the field of education: teachers or students can use PSSD to store teaching materials, research papers, etc., while ensuring the security of sensitive data. When traveling: travelers can use PSSD to store travel plans, hotel reservation information, etc., while ensuring the security of personal data. It can be understood that the application scenarios of PSSD are not limited to the scenarios mentioned above, and other possible scenarios are also applicable.

[0034] like Figure 3 As shown, in another embodiment of the present application, PSSD300 includes: a controller 301, a Bluetooth module 302 electrically connected to the controller 301, a storage chip 303 and an interface 304, an antenna 307 and a buzzer 305 electrically connected to the Bluetooth module 302, and a power module electrically connected to the buzzer 305 and the Bluetooth module 302; the Bluetooth module 302 can send signals and receive information through the antenna 307; the Bluetooth module 302 can also be used to drive the buzzer 305 to alarm when receiving a search message sent by the APP; the power module 306 is used to supply power to the Bluetooth module 302 and the buzzer 305 when the PSSD300 is not connected to the host, so that the PSSD300 operates in anti-loss and search mode.

[0035] When an external Bluetooth device sends a search message through the APP, the Bluetooth module 302 receives the message and drives the buzzer 305 to sound an alarm, thereby helping the user find the PSSD 300.

[0036] In some possible embodiments, the power module 306 may include a rechargeable battery, such as a rechargeable button battery or a polymer battery.

[0037] In some possible embodiments, when the PSSD 300 is electrically connected to the host through the interface 304 , power can be obtained from the host to charge the rechargeable battery.

[0038] To facilitate understanding, let's describe the anti-lost and search modes. Taking Apple's AirTag as an example, PSSD can use Bluetooth signals to broadcast its own device information to the surrounding area. After any Apple terminal receives the broadcast signal, it will upload the location range of the PSSD to the Apple server. The owner of the PSSD can view the location of the PSSD through Apple's FindMy software. When the PSSD owner approaches the PSSD device, he can also connect to the PSSD device via Bluetooth and send a command to make it sound a buzzer, thereby finding the location where the PSSD was lost.

[0039] For the Android system, the basic principles of anti-lost and search modes are similar. PSSD can use Bluetooth signals to broadcast its own device information to the surrounding area. When other Android devices receive these broadcast signals, they can upload the location information of the lost device to a cloud server, such as Google Maps or services provided by specific manufacturers. Users can view the location of the lost device through corresponding applications (such as Google Maps or applications provided by manufacturers). When the user approaches the lost device, he can send commands through the application to make the device emit sounds, such as beeps or ringtones, to help locate it.

[0040] In some possible implementations, the anti-loss and search modes can also be cross-platform, that is, compatible with Apple's AirTag or Google's GoogleTag anti-loss system, adding anti-loss capabilities to PSSD. Whether the product is accidentally left behind or maliciously stolen, it may be possible to recover it through the anti-loss system.

[0041] In some possible embodiments, the PSSD may further include a magnet to enable the PSSD to be adsorbed on a surface of an external device.

[0042] In some possible embodiments, the controller of the PSSD can also be used to dynamically adjust the response time of subsequent verification connection requests based on a preset time interval and the accumulated number of errors when the connection request is received through the Bluetooth module and when the verification fails. It can be understood that when an external Bluetooth device attempts to connect to the PSSD through the preset APP, it will send a connection request containing authentication information (such as a password). The Bluetooth module of the PSSD receives this request and passes it to the controller. If the controller cannot verify the authentication information in the connection request (for example, the password is incorrect), it will reject the request and record the failed verification attempt. The controller can dynamically adjust the response time of subsequent verification requests based on the accumulated number of errors and the time interval. For example, if the verification fails three times in a row, the controller can increase the response time from the initial few seconds to several minutes. By increasing the response time between consecutive failed attempts, the PSSD controller effectively slows down the speed at which potential attackers try different password combinations. This helps protect the PSSD from unauthorized access.

[0043] Those skilled in the art will clearly understand that, for the sake of convenience and brevity of description, the specific working processes and technical effects produced by the above-described devices and equipment can refer to the corresponding processes and technical effects in the aforementioned embodiments and will not be repeated here.
