566 Managing Comments ✦ Status, such as accepted or rejected ✦ Checked State, which can be checked or unchecked Use these filtering options to view only those comments that are relevant to you. Sharing comments You can share your comments with other reviewers who have access to the same PDF document by following these steps: 1. Make sure that the Comments List is visible by clicking the Comments tab on the bottom left of the Document window. 2. Select the comment that you want to export by clicking it (Shift+click for multiple selections). 3. From the Comments List window, choose Options➪Export Selected Comments. The Export Comments dialog box appears. 4. Browse to the location where you want the comments to be saved and give the saved file a new name. You now have a file that includes only the comments’ information, and not the entire PDF file. You can share your file with reviewers who have the same PDF file, and they can choose Options➪Import Comments in the Comments List window to add the comments into their document. You can use this method to avoid send- ing entire PDF files to those who already have the document. Summarizing comments You can compile a list of all the comments from a PDF file into a new, sepa- rate document. To summarize comments, follow these steps: 1. From the Comments List window, choose Options➪Summarize Comments. The Summarize Options dialog box appears. 2. Create a listing of the comments with lines connecting them to their locations on the page by selecting the radio button from the top — Document and Connector Lines on a Single Page. In the Include section, you can choose which comments should be summarized. 53_607466-bk05ch05.indd 56653_607466-bk05ch05.indd 566 5/25/10 8:54 AM5/25/10 8:54 AM Book V Chapter 5 Using Commenting and Annotation Tools 567 Managing Comments 3. Click the Create PDF Comment Summary button. This step creates a new PDF document that simply lists all the com- ments, as shown in Figure 5-3. Figure 5-3: A new PDF document is created, listing all the comments. Enabling commenting in Adobe Reader Acrobat 9.0 Professional makes it easy to include users of the free Adobe Reader in a review process. To include Adobe Reader users in a review, choose Comments➪Enable for Commenting in Adobe Reader. After saving the file, you can share it with users of Adobe Reader, who can then use com- menting and markup tools and save their comments into the file. A user of Adobe Acrobat 9.0 Professional must enable commenting in a PDF file before users of Adobe Reader can add comments to a file. 53_607466-bk05ch05.indd 56753_607466-bk05ch05.indd 567 5/25/10 8:54 AM5/25/10 8:54 AM 568 Book V: Acrobat 9.0 53_607466-bk05ch05.indd 56853_607466-bk05ch05.indd 568 5/25/10 8:54 AM5/25/10 8:54 AM Chapter 6: Securing Your PDF Files In This Chapter ✓ Finding out about security in Acrobat ✓ Using passwords ✓ Setting limits for editing and printing Y ou may think that because you’ve converted your documents to PDF (Portable Document Format) that they’re secure. This isn’t quite true because Adobe Acrobat includes tools for changing text and images, as well as extracting them for use in other files. For example, you can use the Select tool (see Chapter 4 of this minibook) to select and copy a passage of text or the Select Object tool to copy or edit graphics. Applying security provides you with control over who can view, edit, or print the PDF documents you distribute. You can restrict access to certain features, which deters most users from manipulating your files. All Adobe applications recognize and honor security settings applied in Acrobat, but some software ignores Adobe’s security settings or can bypass them all together. For this reason, we recommend that you share your most sensitive PDF documents only when you’ve applied security protection. This way, the only users who can open a file are those who know the password or have the correct certificate, depending upon the type of security applied to the file. In this chapter, we discuss using security protection to limit access to PDF files and show you how to limit what users can do to the contents of your PDF documents. Understanding Password Security By requiring users to enter a password to open and view your PDF files, you limit access to those files so that only certain users can view them. You can also apply security to limit access to certain Acrobat and Adobe Reader fea- tures, such as copying text or graphics, editing the file, and printing. Adobe calls this type of security password security because it requires a password to either open the document or to change the security that’s been applied to the document. 54_607466-bk05ch06.indd 56954_607466-bk05ch06.indd 569 5/24/10 10:29 PM5/24/10 10:29 PM 570 Understanding Password Security Apply security options to limit the opening or editing of your PDF document, restricting these capabilities to users who have been provided the proper password. This is done by clicking the Secure button on the Tasks toolbar. If the Secure button isn’t visible, choose View➪Toolbars➪Tasks. Click and hold down the Secure button in the Tasks toolbar and choose 2 Encrypt with Password to bring up the Password Security - Settings dialog box. In the Password Security - Settings dialog box, choose an Acrobat version from the Compatibility drop-down list. The higher the version of Acrobat, the greater the level of security. Your choice here is based on your needs for security and also the version of Acrobat or Adobe Reader that your audience uses. Lower versions of Acrobat provide more compatibility with the widest number of viewers, as they support much older versions of the free Adobe Reader. In the following list, we explain the compatibility choices before showing you how to enable security in the following sections: ✦ Acrobat 3 and Later: If the users who receive your PDF files may have older versions of the software, you can choose Acrobat 3 and Later from the Compatibility drop-down list to ensure that the recipients can view the PDF file you’re securing. This option provides compatibility for users who may not have updated their software in many years, but the level of security is limited to 40-bit encryption. Although this amount keeps the average user from gaining access to your files, it won’t deter a deter- mined hacker from accessing them and can be easily circumvented by a sophisticated user. ✦ Acrobat 5 and Later: When sharing files with users who have access to Adobe Reader or Adobe Acrobat Version 5 or 6, this option provides expanded security, increasing the security level to 128-bit, which makes the resulting PDF files more difficult to access. Along with the enhanced security, you can also secure the files while still allowing access to the file for visually-impaired users. Earlier versions of security don’t pro- vide this option, but it’s included when you choose either Acrobat 5- or 6-compatible security. ✦ Acrobat 6 and Later: Along with the enhanced security offered with Acrobat 5 compatibility, this setting adds the ability to maintain plain text metadata. In short, this option allows for information about the file, such as its author, title, or creation date, to remain visible while the remainder of the file remains secure. ✦ Acrobat 7 and Later: This choice includes all security options of Acrobat 6 compatibility and also allows you to encrypt file attachments that are part of a PDF file. It uses the Advanced Encryption Standard, which is a very high level of encryption, making it unlikely that an unau- thorized user can decrypt the file without the password. 54_607466-bk05ch06.indd 57054_607466-bk05ch06.indd 570 5/24/10 10:29 PM5/24/10 10:29 PM Book V Chapter 6 Securing Your PDF Files 571 Applying Password Security to Your PDF Documents ✦ Acrobat 9 and Later: Choose this option if your audience is using the latest version of Acrobat and you need more advanced security. The encryption improves to 256-bit AES, making the file much more difficult for even the most determined hacker to access. Applying Password Security to Your PDF Documents Selecting the Encrypt with Password option from the Secure button in the Acrobat task bar limits access to the PDF file. Only those who know the password can open the file. Documents are only as secure as the passwords that protect them. To guard against discovery of a password, use passwords that are six or more characters in length and include at least one number or symbol. Avoid using words in the dictionary and short passwords. For exam- ple, the password potato is less secure than p0tat0, which mixes numbers and letters. To apply password security to a file, follow these steps: 1. With a PDF file open, click and hold the Secure button on the Security taskbar and choose Encrypt with Password. Click OK when the dialog box appears, verifying that you want to apply security to this PDF. The Password Security - Settings dialog box appears, as shown in Figure 6-1. Figure 6-1: The Password Security – Settings dialog box. 54_607466-bk05ch06.indd 57154_607466-bk05ch06.indd 571 5/24/10 10:29 PM5/24/10 10:29 PM 572 Limiting Editing and Printing 2. Choose Acrobat 7 and Later from the Compatibility drop-down list. Although Acrobat 9 and later provides more robust security, few people are using version 9 of Acrobat, making it difficult to distribute the file with this high level of security. 3. Select the Require a Password to Open the Document check box. 4. Enter a password in the Document Open Password text box. You can also add additional security settings, which we outline in the next section. Or you can use this setting as the only security to be applied to the document. If password protection is the only security measure you apply to the document, authorized users can access the document by entering a password. Users with the password may also be able to edit or print the document unless you apply additional security measures. We discuss ways to limit the editing and printing of PDF files in the next section. 5. Click OK. 6. Confirm the password, click OK again, and the dialog box closes. 7. Save, close, and then reopen the PDF file. A password dialog box appears asking for the password to access the secured file. Every time a user accesses the file, he or she will be required to enter a password. Limiting Editing and Printing In addition to restricting viewing of a PDF file, you can also limit editing and printing, restricting users from making changes to your document. This allows users to view a file but not change it. To limit editing and printing of your PDF document, follow these steps: 1. With a PDF file open, click and hold the Secure button on the Security taskbar and choose Encrypt with Password. The Password Security – Settings dialog box opens. 2. In the Permissions area, select the check box labeled Restrict Editing and Printing of the document. You can now specify a password that will be required for readers to edit the file or change the security settings. (See the previous section.) 54_607466-bk05ch06.indd 57254_607466-bk05ch06.indd 572 5/24/10 10:29 PM5/24/10 10:29 PM Book V Chapter 6 Securing Your PDF Files 573 Limiting Editing and Printing With this option selected, you can apply a password for access to fea- tures, such as printing or editing. This password can be different than the password used to open the document — in fact, you don’t even need to use a document open password if you don’t want to, but it’s a good idea to use both of these passwords for sensitive data. If you apply a document open password without a permissions password, it’s easy for an experienced user to bypass the security in the PDF file. 3. In the Change Permissions Password text box, enter a password. Users that enter this permissions password when opening the document can change the file or the security settings. The permissions password can also be used to open the file and provides more privileges than the open password. 4. Choose whether users can print the document by selecting from the Printing Allowed drop-down list. The choices include Low Resolution or High Resolution, or you can pro- hibit printing by choosing None. The settings you choose here apply to anyone who accesses the document and doesn’t know the permissions password. 5. Choose from the Changes Allowed drop-down list (see Figure 6-2) to restrict editing. For the most security, choose None. Figure 6-2: Restrict what users can edit. 54_607466-bk05ch06.indd 57354_607466-bk05ch06.indd 573 5/24/10 10:29 PM5/24/10 10:29 PM 574 Limiting Editing and Printing 6. Select the last two check boxes if desired: • Enable Copying of Text, Images, and Other Content: When deselected, this option restricts copying and pasting of text and graphics from a PDF file into other documents. Selecting this option lets users extract text and images from a file by using the simple Copy and Paste commands. • Enable Text Access for Screen Reader Devices for the Visually Impaired: When you choose Acrobat 5 or Later from the Compatibility drop-down list at the top of the dialog box, you can also select this check box to allow visually impaired users to have the PDF file read aloud to them. 7. When you’re satisfied with the settings, click OK. Choosing more advanced security settings, and choosing the latest version of compatibility, runs the risk of your file not being visible to many users that may not have upgraded. Always understand your audience and the soft- ware versions they’re using before distributing files. 54_607466-bk05ch06.indd 57454_607466-bk05ch06.indd 574 5/24/10 10:29 PM5/24/10 10:29 PM Book VI Dreamweaver CS5 55_607466-pp06.indd 57555_607466-pp06.indd 575 5/24/10 10:30 PM5/24/10 10:30 PM [...]...
