Problems solved by technology

However, during use, if the user turns off the camera permission of the application, an error will be caused when the user needs to take a photo; occurs, the user has no way of knowing
Therefore, the second prior art also makes it difficult for users to identify whether the application program has malicious candid behavior
This may lead to the violation of user privacy
[0007] Therefore, neither of the above two existing technologies can completely prevent malicious applications from sending pictures from the terminal device without the user's confirmation and consent, which may cause the user's privacy to be violated

Embodiment 1

[0046] figure 1 A flowchart showing a method for sending pictures according to an embodiment of the present invention.

[0047] Such as figure 1 As shown, the picture sending method mainly includes the following steps:

[0048] Step S110, generating and outputting a sending confirmation request for the picture to be sent;

[0049] Step S120, judging whether a transmission confirmation operation performed by the user for the transmission confirmation request is detected, and proceed to step S130 if the transmission confirmation operation is detected, otherwise, continue to wait until the transmission confirmation operation is detected;

[0050] Step S130, attaching a mark to the picture;

[0051] Step S140, verifying the picture;

[0052] Step S150, judging whether the picture has passed the verification, and proceeding to step S160 if it is determined that the picture has passed the verification, otherwise directly end this process without sending the picture; and

Embodiment 2

[0059] figure 2 A flow chart of a method for sending pictures according to another embodiment of the present invention is shown. figure 2 neutralize figure 1 Steps with the same numbers have the same functions, and for the sake of brevity, detailed descriptions of these steps are omitted. and, if figure 2 as shown, figure 2 The method shown is the same as figure 1 The main difference of the shown method is that, based on the HMAC (Hash-based Message Authentication Code, Hash-based Message Authentication Code) operation, the tag is added and the verification is performed.

[0060] Specifically, if figure 2 As shown, the additional mark and mark-based verification in the image sending method may specifically include:

[0061] Step S211, in the case of detecting the transmission confirmation operation performed by the user for the transmission confirmation request, using the attribute information of the picture and the preset first key to perform the first HMAC operati...

Embodiment 3

[0073] image 3 A block diagram of a picture sending device according to an embodiment of the present invention is shown.

[0074] Such as image 3 As shown, the image sending device mainly includes a confirmation unit 310 , a marking unit 320 , a verification unit 330 and a sending unit 340 . Wherein, the confirmation unit 310 is mainly used for generating and outputting a transmission confirmation request for the picture to be transmitted, and detecting a transmission confirmation operation performed by the user on the transmission confirmation request. The marking unit 320 is connected to the confirming unit 310 and is mainly used to add a mark to the picture when the confirming unit 310 detects a sending confirmation operation. The verification unit 330 is connected to the marking unit 320 and is mainly used for verifying pictures. The sending unit 340 is connected with the verification unit 330 and is mainly used for sending the picture from the terminal device via the...

Abstract

The invention discloses an image transmission method, device and terminal device. The method comprises: generating and outputting transmit confirmation requiry according to the image to be transmitted; attaching a lag to the image when detecting the user has made a transmit confirmation operation according to the transmit confirmation requiry; confirming the image; transmitting image via network from the terminal device on the premise of that the image is verified; wherein the transmit confirmation requiry is used for inquiring the user to confirm if the image can be transmitted, the transmit confirmation operation is executed by user, with predetermined style and on the terminal device, in response to transmit confirmation requiry. The image transmission method ,device and terminal device of the invention can ensure that the image transmitted from the terminal device is consented to transmit by the user, thereby preventing unauthorized photographing or stealing from the terminal device and invasion of privacy of the user, effectively protecting data safety of the user.

Description

technical field [0001] The present invention relates to the field of communication technology, in particular to a method and device for sending pictures and a terminal device. Background technique [0002] With the development of communication technology, currently most terminal devices such as smart phones are equipped with cameras, such as not only rear cameras but also front cameras. Some malicious applications can pretend to be regular applications to lure mobile phone users to download them. When users use the malicious application, the malicious application will send pictures without the user's confirmation and consent, and put the user on the terminal device. The photos obtained by taking pictures or downloaded pictures are sent from the terminal device, resulting in violation of user privacy. [0003] For example: some malicious applications with the function of taking pictures can secretly take pictures without the consent of the user through steps such as disguisi...
