The fast development of communication and technology has created new challenges to transfer data securely. The techniques widely used to secure the data are cryptography and steganography. This paper presents a video steganography method to secure the information to be transmitted. Information transmitted can be an image, audio, text or video. This article presents a new technique that embeds data in the spatial domain of the cover video frame. The method employs chaotic maps to generate Random Positions (RP) to hide the information bits, random numbers for selecting the frames at which the information to be hidden and confusion order to encrypt the cover frame. The video frame is first selected based on Frame Selection (FS) is encrypted by applying Confusion Order (CO) and then embedding is carried out on the random positions generated. After embedding, the decrypted cover frame is replaced in a video sequence for transmission. This method provides three-level security in extracting the hidden secret information and also 25% of embedding capacity. Experimental outcomes (PSNR and payload) confirm that the method is competent.

通信和技术的飞速发展为安全传输数据带来了新的挑战。广泛用于保护数据安全的技术是密码术和隐写术。本文提出了一种视频隐写方法，以保护要传输的信息。传输的信息可以是图像，音频，文本或视频。本文介绍了一种新技术，可将数据嵌入封面视频帧的空间域中。该方法采用混沌映射来生成用于隐藏信息位的随机位置（RP），用于选择要在其处隐藏信息的帧的随机数以及用于对覆盖帧进行加密的混淆顺序。首先基于帧选择（FS）选择视频帧，方法是应用混淆顺序（CO）对其进行加密，然后在生成的随机位置执行嵌入。嵌入后，将解密的封面帧替换为视频序列进行传输。此方法在提取隐藏的秘密信息方面提供了三级安全性，并且还提供了25％的嵌入容量。实验结果（PSNR和有效载荷）证实了该方法的有效性。
