摘要

Telegram是一个通讯平台，每月有数百万用户。因此，它是隐写信息的可能载体。我们研究了使用Telegram作为具有隐写内容的图像的信使服务的可行性，特别是我们使用F5作为概念证明。我们评估最佳分辨率和质量设置，以实现最大可能的有效载荷大小。为了支持在Telegram上传输更长的消息，我们设计了一个具有定期图像时间表的覆盖通道，以具有高带宽。我们发现，在JPEG质量设置为82时，消息传输的最佳分辨率是2560x2560。这个配置允许我们发送平均每幅图像81千字节的数据。

Using Telegram as a carrier for image steganography: Analysing Telegrams API limits

Telegram is a messaging platform with millions of users per month. For this reason, it is a possible vector for steganographic messages. We investigate the feasibility of using Telegram as a messenger service for images with steganographic content, specifically we use F5 as a proof of concept. We evaluate the optimal resolution and quality settings to achieve the highest possible payload size. In order to support longer message transfers over Telegram, we design a cover channel with a regular schedule of images to have a high bandwidth. We found that the optimal resolution for message transfers is 2560x2560 at JPEG quality settings of 82. And that this configuration allows us to send an average of 81 kilobytes of data per image.
