Problems solved by technology

[0002] With the rapid development of Internet technology, it has become a common behavior for users to convey information to other people in the form of screenshots, but the information expressed in screenshots is not comprehensive, especially when users feedback app problems, they often use screenshots supplemented by text The way to describe the problem is to describe the problem. The screenshot cannot include information such as the network status of the user at the moment of the screenshot, the data sent by the network, etc. It is difficult for technicians to accurately locate the app problem based on the screenshot.
[0003] At present, using the existing technology of embedding information in pictures cannot effectively embed information when taking screenshots on the client side, and errors such as white screens are prone to occur
And in the process of compressing the embedded pictures and sharing them through communication tools, the embedded information is easy to be confused and lost

Abstract

The embodiments of the present application disclose a method and an apparatus for embedding information in a picture. A specific implementation of the method includes: using a first transformation matrix to convert the spatial domain data matrix of the screenshot into an original frequency domain coefficient matrix; performing first rounding, quantization and second rounding on the original frequency domain coefficient matrix to obtain an intermediate Frequency domain coefficient matrix, in which, the integer part of the source data is retained by the first rounding and the second rounding, and the decimal part of the source data is removed; the information to be embedded is embedded into the DC coefficient of the intermediate frequency domain coefficient matrix to obtain the embedded information The frequency domain coefficient matrix of the embedded information is used to convert the frequency domain coefficient matrix of the embedded information into the spatial domain data matrix of the embedded information; based on the spatial domain data matrix of the embedded information, a picture of the embedded information is generated. This embodiment achieves the effectiveness and stability of embedding information in pictures.
