Description

一种基于智能终端的水印添加方法及水印添加系统 技术领域
本发明涉及智能终端领域，尤其涉及一种基于智能终端的水印添加方法及水印添加系统。
背景技术
随着智能终端在人们的日常生活中的普及化，智能终端成为了人们生活中越来越不可分割的一部分。随着科学技术的日益发展，智能终端不断推陈出新，具备的功能也越来越多样化，例如，支付、听歌、上网、点餐、看书等，为人们工作生活等各方面带来各种各样的资讯信息，极大丰富了人们信息获取的范围。
如今，为了给用户提供更为便捷的使用体验，大多数智能终端都具有将语音转换为文字输出的功能，但是目前这类功能仅仅局限于在特定应用程序中使用，并且通常智能在社交应用程序中实现。
此外，基于数字化网络平台的出现，对网络资料(如：多媒体、文档、软件等)保护的需求也越来越高。目前比较常用的保护方法为嵌入水印。水印技术是将一些标识信息(即数字水印)直接嵌入数字载体当中(包括多媒体、文档、软件等)或是间接表示(修改特定区域的结构)，且不影响原载体的使用价值，也不容易被探知和再次修改。但可以被生产方识别和辨认。通过这些隐藏在载体中的信息，可以达到确认内容创建者、购买者、传送隐秘信息或者判断载体是否被篡改等目的。数字水印是保护信息安全、实现防伪溯源、版权保护的有效办法，是信息隐藏技术研究领域的重要分支和研究方向。
水印技术基本上具有下面几个方面的特点：
1.安全性：数字水印的信息应是安全的，难以篡改或伪造，同时，应当有较低的误检测率，当原内容发生变化时，数字水印应当发生变化，从而可以检测原始数据的变更；当然数字水印同样对重复添加有很强的抵抗性；
2.隐蔽性：数字水印应是不可知觉的，而且应不影响被保护数据的正常使用；不会降质；
3.鲁棒性：该特性适用于鲁棒水印。是指在经历多种无意或有意的信号处理过程后，数字水印仍能保持部分完整性并能被准确鉴别。可能的信号处理过程包括信道噪声、滤波、数/模与模/数转换、重采样、剪切、位移、尺度变化以及有损压缩编码等；
4.敏感性：该特性适用于脆弱水印。是经过分发、传输、使用过程后，数字水印能够准确的判断数据是否遭受篡改。进一步的，可判断数据篡改位置、程度甚至恢复原始信息。
然而，目前的水印技术主要仍局限于输入文字添加数字水印，需要用户在智能终端中手动输入文字，不便于用户的实际使用，尤其不便于水印字符数较长的情况。
因此，为了克服现有技术的缺陷，对现有技术进行进一步地改进，需要提出一种基于智能终端的新型的水印添加方法及水印添加系统，不局限于所使用的应用程序，能够将输入的语音直接转化为文字型水印，转化精确度高，便于用户的使用，为用户提供一种更好的使用体验。

本发明提供的水印添加方法及水印添加系统，不局限于所使用的应用程序，通过上述方法及系统用户能够将输入的语音直接转化为文字型水印输出。此外，本发明提供的水印添加方法及水印添加系统所能识别的语音不仅仅局限于标准的男声或女声，对童声等其他声色的语音也能精确识别，转化精确度高，便于用户的使用，为用户提供一种更好的使用体验。
如图1所示，为符合本发明实施例的一种基于智能终端的水印添加方法的流程示意图。本发明实施例提供了一种基于智能终端，如手机、平板电脑等智能设备的水印添加方法，具体地，包括如下步骤：
所述智能终端采集一语音；
具体地，启动智能终端如手机、平板电脑等设备，找到智能终端界面上的水印添加应用程序的图标，点击水印添加应用程序图标，打开水印添加应用程序。进入水印添加应用程序后，选择开启智能终端的麦克风。麦克风开启，获取一语音，完成语音采集。
优选地，所述语音包含男声、女声、童声中的一种或多种。
优选地，智能终端通过麦克风采集用户录入的语音，本发明实施例中提供的一种基于智能终端的水印添加方法中所涉及的语音包含各种声色，对语音的识别不仅仅局限于标准的男声、女声，也包含童声等其他声色的语音。
识别所述语音中的语音信息，以生成一与所述语音信息对应的语音数据；
具体地，待智能终端通过麦克风采集到一语音时，完成采集语音的步骤后，基于智能终端的水印添加方法进一步地对该语音中包含的语音信息进行识别，并根据该语音信息生成一与之相应的语音数据，用于后续处理。例如，当智能终端识别出采集到的语音包含“智能终端”的语音信息后，会根据“智能终端”的语音信息生成与之相应的文字数据，即通过数据的方式表达“智能终端”。
优选地，于所述识别所述语音中的语音信息，以生成一与所述语音信息对应的语音数据的步骤中，所述水印添加方法进一步包含去除所述语音信息中的噪点。
优选地，对采集所得的语音信息进行转化的步骤中，本发明实施例中的水印添加方法进一步包括对获取所得的语音信息的去噪处理，以确保转化成的语音数据不包含环境声音、背景杂音等。
将所述语音数据转化为一与所述语音数据对应的文字数据；
待从采集到的语音中获取到语音中所包含的语音数据后，本发明实施例中的水印添加方法包含将获取所得的语音数据转化为与该语音数据对应的文字数据。通过改变数据的格式，实现语音转化到文字的第一步。
合成所述文字数据，以生成一与所述语音信息匹配的文字信息；具体地，通过改变数据的格式获得经语音数据转化后的文字数据后，合成转化所得的文字数据，即可获得一相应的文字信息，该文字信息与先前采集所得的语音信息相对应。
根据所述文字信息，生成一与所述语音匹配的水印；
具体地，当智能终端通过合成由语音数据转化得到的文字数据获取相应的文字信息后，自动根据该文字信息生成一水印。该水印所显示的文字与先前采集所得的语音相匹配。即，先前采集的语音经转化成为一文字型水印。例如，先前采集所得的语音为“智能终端”的语音，最后经智能终端转化生成一“智能终端”字样的水印。

优选地，本发明实施例中提供的一种基于智能终端的水印添加方法在生成一与语音匹配的水印的步骤与将所述水印嵌入一图像中的步骤之间进一步包括储存已生成的水印的步骤。例如，当智能终端根据用户输入的“智能终端”语音生成一“智能终端”字样的水印后，暂时不想直接将水印嵌入图像中时，可以选择将已生成的水印储存于智能终端中，作备用，便于用户随时调用。
将所述水印嵌入一图像中，以生成一带有所述水印的水印图像；
具体地，待智能终端根据采集所得的语音转化生成一水印后，可以进一步将所得水印嵌入图像中。以此，图像嵌入由输入的语音转化而得的文字型水印，生成一带有与输入语音匹配的字样的水印图像。水印图像中的水印文字无需用户手动输入，仅需输入语音即可转化生成。
优选地，当储存多个所述水印后，将所述水印嵌入一图像的步骤中进一步包含选择需要嵌入的所述水印。
具体地，根据采集所得的多个语音转化生成多个水印后，若用户暂时无需使用该水印时，为了避免重复制作，可以选择储存该水印，以备后续用户需要的时候使用。故，当智能终端中存有多个水印时，将水印嵌入图像的步骤中需进一步包含在储存于智能终端中的水印中选择需要嵌入的水印。

具体地，当转化模块通过通讯连接将转化所得的文字数据发送到合成模块中后，合成模块根据接收所得的文字数据合成在处理后生成一水印，生成的水印与先前获取到的语音信息匹配。当合成模块合成了一水印后，通过通讯连接，将该水印发送到水印添加系统的嵌入模块中。
优选地，所述系统进一步包含一储存模块，与所述合成模块和所述嵌入模块通讯连接，用于储存所述水印。优选地，本发明提供的一种基于智能终端的水印添加系统进一步包含一储存模块。该储存模块与合成模块和嵌入模块建立通讯连接。若暂时不需要嵌入生成的水印时，在合成模块通过通讯连接将水印发送到水印添加系统中的嵌入模块中之前，可以进一步通过通讯连接将合成所得的水印发送至储存模块中储存。待需要嵌入该水印时，储存模块再通过通讯连接将上述水印发送至嵌入模块中嵌入。即在合成模块将合成出的水印发送到嵌入模块形成具有水印图像之前，合成模块进一步包括将合成的水印发送至储存模块储存，作备用。
所述嵌入模块与所述合成模块通讯连接，将所述水印嵌入一图像中，以生成一带有所述水印的水印图像。
具体地，待合成模块根据采集所得的语音转化生成一水印后，嵌入模块可以进一步将所得水印嵌入图像中。嵌入模块与合成模块通讯连接。通过通讯连接合成模块将合成的水印发送至嵌入模块中。嵌入模块将由语音转化而来的水印嵌入图像中，以此，生成一带有与输入语音匹配的字样的水印图像。水印图像中的水印文字无需用户手动输入，仅需采集模块采集到用户输入语音即可转化生成。
优选地，当所述储存模块储存多个所述水印后，所述嵌入模块进一步包含选择需要嵌入的所述水印。优选地，当合成模块将合成出的多个水印发送到储存模块中储存后，若储存模块需要将水印发送到嵌入模块，嵌入模块准备嵌入水印时，嵌入模块进一步包括对所嵌入水印的选择。即，本发明提供的一种基于智能终端的水印添加系统中的嵌入模块进一步包含对水印添加的选择和设置。
采用本发明提供的一种基于智能终端的水印添加方法及水印添加系统后，用户可以通过智能终端直接将其所获取语音转化为一与语音匹配的文字型水印。该水印添加方法及水印添加系统操作简便，无需通过用户手动输入实现，且运行过程不依赖于某一应用程序的运行，也不受运行的应用程序限制。根据本发明提供的水印添加方法及水印添加系统，能够对用户输入的语音准确识别，并且不局限于输入语音的声色，例如，男声、女声及童声等。基于该水印添加系统，不仅可以对标准的男女声进行识别分析，也可对童声等其他声音作识别，故采用本发明提供的一种基于智能终端的水印添加系统后，语音到文字的转化具有较高的精准度，水印的合成更为准确。此外，根据本发明提供的水印添加方法，用户还能够进一步选择嵌入的水印。因此，基于本发明提供的水印添加方法及水印添加系统能为用户提供一种更为便捷的使用体验。
