Embodiment 1

[0080] This embodiment provides a method for using deep learning to identify fraudulent text messages, such as figure 1 shown, including steps:

[0081] S11: Obtain the text data of the SMS sample and perform word segmentation processing;

[0082] S12: using Word2Vec to convert the text data after halving into word vectors;

[0083] S13: Using the LSTM algorithm to convert word vectors into sentence vectors;

[0084] S14: using the sentence vector as the input vector of the softmax classifier to train the deep learning model;

[0085] S15: Identify fraudulent text messages according to the output result of the softmax classifier of deep learning after training;

[0086] S16: If it is determined to be a fraudulent short message, intercept the short message.

[0087] In recent years, deep learning algorithms have been applied to the field of natural language processing and have achieved better results than traditional models. In natural language processing, the commonly use...

Abstract

The invention discloses a method and a system for recognizing a fraud short message by using deep learning, used for solving the problem that an algorithm is not high in recognition accuracy due to the fact that the features of the fraud short message is ever-changing. The method comprises the steps of acquiring text data of a short message sample and performing word segmentation treatment; usingWord2Vec to convert the text data that is subjected to the word segmentation into word vectors; using an LSTM algorithm to convert the word vectors into sentence vectors; using the sentence vectors asinput vectors of a softmax classifier to train a deep learning model; and recognizing the fraud short message according to an output result of the trained and deeply learned softmax classifier. According to the method and system for recognizing the fraud short message by using deep learning provided by the invention, the capacity of accurately recognizing the fraud short message is improved.

Description

technical field [0001] The invention relates to the technical field of communication security, in particular to a method and system for identifying fraudulent short messages by using deep learning. Background technique [0002] SMS, as a carrier of information transmission among massive customers, sets up an effective channel for mutual communication. With the widespread use of short messages, the phenomenon of fraudulent information transmitted through short messages has become more and more serious, which has brought great inconvenience to mobile phone users for normal information exchange, and more and more users have been deceived and suffered unbearably. Word. [0003] While creating economic benefits, SMS has also brought serious social costs and cultural losses to operators. [0004] At present, the research on fraud SMS identification is mainly the combination of feature extraction and traditional machine learning algorithms, but feature extraction requires a lot o...
