other file formats include: pages, video, audio, and other files are converted into layout data stream files.

The method for dynamically inserting pages, moving bits and hiding and displaying the multi-format file subscription comprises the following steps:

s100, a reader acquires an original text list to be read in a cloud server, loads and analyzes corresponding files, wherein the files comprise layout files and/or layout data stream files, and combines file catalogues to form a new file catalogue, and multiple files are combined to unify experience reading;

s200, registering related events between two adjacent pages or two adjacent files, wherein the related events comprise one or more of insertion events, stealing events, hiding events and deleting events,

it should be noted that, among others,

the insertion event is used for inserting and signing between two adjacent pages and/or signing on the pages, where the pages include the page of the layout file loaded originally and also include the new page formed by the later inserting and signing, such as: and combining the content shown in fig. 4, triggering an insertion event on the current display page, inserting a blank page, setting the paper size of the blank page according to the requirement, and selecting handwriting input on the blank page according to the requirement to carry out handwriting signing.

The hiding event is to hide any one or more of the existing file resources, signature content and specified pages in the file loaded by the reader; the hiding manner includes hiding a whole page of content and/or hiding local content of a page, such as:

with the content shown in fig. 5, the current page is hidden, i.e. the current page is not displayed in the processes of turning and viewing, and the page number is updated accordingly, and the page number of the next page becomes the page number of the current page;

with reference to the contents shown in fig. 6-1, the selected area is hidden, and an opaque suspension layer is covered on the selected area;

in combination with the content shown in fig. 6-2, a further way of hiding the selected area is to cover an opaque suspension layer on the selected area, obtain the content of the corresponding area on the next page of the page where the selected area is located, render the obtained content on the corresponding suspension layer, and set a frame effect around the suspension layer, so that the currently hidden area forms a visual hollowed-out effect;

case two, triggering a hidden event, including

Selecting layout file content on a designated page (a page before or after the point triggering the hiding event), existing file resources and signature content on a baseplate of the designated page (a page before or after the point triggering the hiding event) to be hidden;

in case three, a deletion event is triggered,

selecting existing file resources and/or signing content on a baseplate of a designated page (a page before or after a point position triggering a deletion event) to delete;

in the fourth case, a bit-moving event is triggered,

firstly, selecting a specific page or pages, shifting the page to the front and the back of any page in an original set, and rearranging file catalogues, wherein the original set refers to the current combined and displayed read file;

secondly, selecting a certain area or character in a certain page of the original set through screen capturing or frame drawing, shifting the part of content as a whole page to any position in the original set, synchronizing the file catalogue with a new page, and covering an opaque suspension layer at the position corresponding to the original page (namely, the position of the certain area or character originally selected through screen capturing or frame drawing);

the method comprises the steps that firstly, encryption operation is carried out on the content of an expansion file when the expansion file is stored, HASH operation is carried out on the content of the expansion file, wherein the encryption operation comprises SM4 and RSA, a user name and a password in a reader can be obtained when the expansion file is stored, and the password of a user is used as an encryption key to ensure that the file cannot be revealed; the encrypted file is subjected to HASH operation, and the HASH operation method comprises MD5 and SM3 so as to ensure that the file cannot be tampered;

the mapping relation between the content formed by the newly added file resource or the signature of the insert and the file is stored in the cloud server together with the expansion file.

In some specific implementations of the present invention,

registering related events between two adjacent pages or between two adjacent files displayed in a presentation window of the reader;

when triggering a related event, caching layout file content corresponding to the related operation, and synthesizing the corresponding layout file content and a result of the related operation to form a new merged directory file;

in the process that the file is triggered to operate, the operation information of each step is synchronously recorded in a mirror image mode to form a series of file versions, the record changes form an expansion file, the expansion file records the dynamic changes of each time of file storage, and the stored file is small in size; a certain version can be selected for restoration and secondary processing treatment;

and removing the cached format file content when the application program of the method for executing the dynamic insert, the bit-moving and the hidden display of the multi-format file contract is exited.

When the transparent suspension layer simultaneously displays a plurality of pages of files, the transparent suspension layer of the plurality of pages is constructed corresponding to the plurality of pages of files.

The method described in the embodiment can edit and delete the layout file and the corresponding expansion file each time (repeated operation can be performed), but the information content of each operation can be recorded, so that the tracing is convenient, or multi-version inquiry is convenient.
